On another website, I have had a contact form but it was missing some functionality. For instance, it stored the input in files on a web server instead of emailing them. That was fixed more easily than expected using the PHP mail function. Even so, it remains useful to survey corresponding documentation on the w3schools website.
The other changes affected the way the form looked to a visitor. There was a reset button and that was removed on finding that such things are out of favour these days. Thinking again, there hardly was any need for it any way.
Newer additions that came with HTML5 had their place too. Including user hints using the placeholder attribute should add some user friendliness although I have avoided experimenting with browser-powered input validation for now. Use of the required attribute has its uses for tell a visitor that they have forgotten something but I need to check how that is handled in CSS more thoroughly before I go with that since there are new :required, :optional, :valid and :invalid pseudoclasses that can be used to help.
It seems that there is much more to learn about setting up forms since I last checked. This is perhaps a hint that a few books need reading as part of catching with how things are done these days. There also is something new to learn.
Though I am writing this in Firefox Developer Edition, I stuck it out with Firefox ESR while plugin developers caught up with the new extension model put in place for Firefox Quantum. Eventually, heavy memory consumption and sluggish rendering forced me to move along even if the addon bar continues to be missed.
During my time of sticking with Firefox ESR, I often turned to Opera when I needed something more speedy and it was then that I found videos playing automatically in loading web pages. Twitter was one offender as was YouTube though it is possible to turn off such things for the former by going to the Accessibility section of your user account settings.
In Opera, I wanted to have a more universal solution and found out where the Experiments section could be found. Though there is a need to realise that there may be changes in the future, entering the opera://flags in the address will get you there. Then, you need to look for Autoplay policy unless you have used the more direct address of opera://flags/#autoplay-policy. After that, you need to change the setting to Document user activation is required and that should sort things. If not, a browser restart will complete the task.
A new feature came with Firefox 44 that only recently started to come to my notice with Yahoo Mail offering to set up browser notifications for every time when a new email arrives there. This is something that I did not need and yet I did not get the option to switch it off permanently for that website so I was being nagged every time I when to check on things for that email address, an unneeded irritation. Other websites offered to set up similar push notifications but you could switch these off permanently so it is a site by site function unless you take another approach.
That is to open a new browser tab and enter about:config in the address bar before hitting the return key. If you have not done this before, a warning message will appear but you can dismiss this permanently. Once beyond that, you are presented with a searchable list of options and the ones that you need are dom.webnotifications.enabled and dom.webnotifications.serviceworker.enabled. By default, the corresponding entries in the Value column will be true. Double-clicking on each one will set it to false and you should not see any more offers of push notifications that allow you get alerts from web services like Yahoo Mail so your web browsing should suffer less of these intrusions.
One thing that I notice with Firefox installations in both Ubuntu and Linux Mint is that a dialogue box appears when closing down the web browser asking whether to save the open session or if you want to have a fresh session the next time that you start it up. Initially, I was always in the latter camp but there are times when I took advantage of that session saving feature for retaining any extra tabs containing websites to which I want to return or editor sessions for any blog posts that I still am writing; sometimes, composing the latter can take a while.
To see where this setting is located, you need to open a new tab and type about:config in the browser’s address bar. This leads to advanced browser settings so you need click OK in answer to a warning message before proceeding. Then, start looking for browser.showQuitWarning using the Search bar; it acts like a dynamic filter on screen entries until you get what you need. On Ubuntu and Linux Mint, the value is set to true but false is the default elsewhere; unlike Opera, Firefox generally does not save sessions by fault unless you tell it to that (at least, that has been my experience anyway). Setting true to false or vice versa will control the appearance or non-appearance of the dialogue box at browser session closure time.
Not before time, the GNOME project has set up a central website for GNOME Shell extensions. It seems to be in the hands of extension developers to make GNOME 3 more palatable to those who find it not to their taste in its default configuration. If you are using Firefox, installation is as easy as clicking the ON/OFF icon for a particular plugin on its web page and then selecting install on the dialog box that pops up. Of all the browsers that you can use on GNOME, it seems to be Firefox that is only one that has this ability for the moment. The website may have the alpha legend on there at the moment but it works well enough so far and I have had no hesitation in using it for those extensions that are of interest to me. This is an interesting development that deserves to stay, especially when it detects that a plugin is incompatible with your version of GNOME. Currently, I use GNOME 3.2 and it pops up a useful menu for deactivating extensions when the desktop fails to load. That’s a welcome development because I have had extensions crashing GNOME 3.0 on me and running the GNOME Tweak Tool on the fallback desktop often was the only alternative. GNOME 3 seems to be growing up nicely.
