Opera and table display

I have encountered something very strange with my hillwalking blog and I have to admit that am at something of a loss as to how to resolve it. Opera (version 9.x), it seems, is not displaying the date corresponding to the first post of a particular month. You can see the effect on the right for the current month and, yes, the tenth of the month has a post associated with it. What compounds the mystery is that the same issue doesn’t affect this blog, so some further investigation is very much in order. However, the cascading element of CSS doesn’t help much when trying to track down the cause of this sort of thing. While, it’s irritating, I don’t have any definite answers yet and so would appreciate some suggestions. In the meantime, I’ll be staying on the lookout for a fix. Curiously, all’s fine on Firefox and IE.

Trying out Firefox 3 Beta 3 on Ubuntu

Keeping an eye on future browser releases helps to avoid any shocks when maintaining publicly available websites. Therefore, it should come as no surprise that I have been giving Firefox 3 a whirl. As it happens, I have had it going on both Windows and Ubuntu. With the former, I have not encountered any obvious problems but am wondering if the new bookmarking system will mean anything to me. For installation on Ubuntu, I used the following command (I think that I culled it from Tombuntu but can’t remember off hand…):

wget -P ~ ftp://ftp.mozilla.org/pub/firefox/releases/3.0b3/linux-i686/en-US/firefox-3.0b3.tar.bz2 && tar xjf ~/firefox-3.0b3.tar.bz2 -C ~

The nice thing about the above is that it places the test installation in your home directory and away from Firefox 2. It also works regardless of what Linux distribution you have. The profiles get shared between versions so a backup would be a good idea before you start to tinker. As with the Windows version, page loading and rendering is faster in the new version but I found a problem with printing that I hope will get sorted before the final release. Another area for attention is font rendering: it could sharper for sans serif fonts on Ubuntu and serif fonts on Windows. Otherwise, it works well on both platforms and I like the way that open windows are saved on exit, a very good idea carried over from Opera.

Online favicon.ico creation

I recently updated the icon that appears beside this blog’s address in the address bar and bookmarks menus of some browsers. I gave it a go in GIMP but I seemed to get no joy. I pottered out on the web to discover what I might have done wrong only to find Dynamic Drive offering online favicon.ico creation. Out of curiosity, I decided to give the thing a whirl and download the result to upload onto my web server. GIF’s, JPG’s PNG’s and BMP’s with a size less than 150 KB are accepted and it did work for me.

A Firefox a day?

No sooner have we received Firefox 2.0.0.10 than they have already started talking about 2.0.0.11. Apparently, the latest update broke support for a tag that I have never used: canvas. This is stuff that makes you wonder about their quality control.

Because the 2.0.0.10 was a security update, Ubuntu volunteered it to me without any effort on my part. However, I am using Ubuntuzilla so I didn’t get the update coming through to my browsing world without further intervention. Launching Firefox using the gksu command allowed me to update the thing like I have been doing on Windows: Help > Check for Updates… I have got a more permanent check set up now thanks to my issuing the following command:

ubuntuzilla.py -a installupdater -p firefox

A different Firefox II: cross-platform font display issues

One of the things that I have been sorting out on this blog is how the fonts appear in Firefox running on Ubuntu. Even with the same fonts and the same browser, serif fonts were being displayed smaller and appeared more fuzzy in Linux than in Windows. And that’s even with the font sharpening that comes with turning on Ubuntu’s visual effects. So, there was a spot of swapping between Ubuntu and Windows (running on VMware) while I was increasing font sizes to make legibility better on the Linux side without things going all Blue Peter on Windows. Along the way, I added a mention of the Ubuntu font ae_AlArabiya in the CSS to further spruce up things. In my earlier web building efforts, I was having to make serif fonts bigger because of those serifs. From the on-screen legibility point of view, there’s a lot to be said for sans serif fonts and I may yet alter this blog’s theme to use them instead but I’ll ponder the idea a bit more before taking the plunge.

A different Firefox…

On Ubuntu, I made a move to using Ubuntuzilla‘s deployment of Firefox. Because Firefox’s Gecko engine is used by other parts of Ubuntu, any Firefox updates issued by Mozilla don’t come through straight away. The idea of using Ubuntuzilla is that you get Mozilla’s latest, be it Firefox, Thunderbird or Seamonkey, without having an impact on the rest of the Linux installation; Ubuntu’s Firefox is left in place but you are now presented with the vanilla Firefox for all your web surfing needs. Visually, there’s not much change but for the built-in Firefox application fonts coming through in the new instance, a strange sight when you see Ubuntu’s more subtle alternatives everywhere else. I tried the new tack to see if picked up RealPlayer in place of Xine but that sadly has not been the case. Nevertheless, I now have 2.0.0.9 and the latest improvements this side of version 3.

Importing bookmarks into Firefox

Moving from one operating system to another like I have means that a certain amount of migration is in order. I have already talked about migrating my email but there are lesser acts too. One of these is carrying across bookmarks into the new world. This should be an easy thing to achieve and, for the most part, it is. However, the Import… entry on the File menu of the main browser only brings in bookmarks from other applications. To get more flexibility, you need to open up the Bookmarks Manager window from the Bookmarks menu (Organise Bookmarks… is the entry that you need). The File menu of the Bookmarks Manager has entries named Import… and Export…; their functions should be very apparent. The former will read from a file, very useful if you do not want to disrupt what you already have. Another migration option is the potentially disruptive act of copying in an alternative bookmarks.html file into your Firefox profile folder and overwriting the one that’s already there.

Faster IE7 phishing monitoring

The standard phishing detection that comes with IE7 really does slow things down when it comes to navigating web pages. In contrast, the option offered as part of Norton 360 is much faster. So much so that you hardly notice that it’s there at all. When I restored IE7 on my PC and ran it for the first time, Norton asked me to be its default fraud detection and I was away from there. Norton 360 offers nothing for Firefox, my preferred and default option but there may be plug-ins that address that need.

Firefox spell checking: getting rid of a mispelling from your dictionary.

Mozilla Firefox includes a spell checker and like any such function, it offers a chance to add words to a custom dictionary. Of course, you can also add misspellings too and these definitely need to be removed. With Word, it’s a matter of looking for custom.dic and deleting the nefarious item. With Firefox, it’s similar, at least on Windows anyway. The file that need to edit is persdict.dat and you’ll find it in C:\Documents and Settings\[user name]\Application Data\Mozilla\Firefox\Profiles\[random name].default. My search for the relevant information took me over to Lifehacker.

Update 2012-12-11: For users of Linux, the location of the above file is as follows: /home/[user id]/.mozilla/firefox/[random name].default. Once you find persdict.dat in there, the required editing can be perfomed.

Adblock Plus

I finally had enough of internetnews.com’s intrusive CPU-eating ads and remembered that there was a Firefox add-on for the job. I have snagged Adblock Plus and can vouch that for its effectiveness. It also works with AccuWeather.com, a site about which I complained a while back. I just wonder why I didn’t thin of this earlier; it certainly beats what ZoneAlarm could do. Now, I see why its functionality has raised some hackles but if advertisers didn’t overdo it in the first place, there would have been no problems. Well, that’s marketing for you… And yes, we do want the right to ignore ads.
