Hi Firefox start to take a lot of CPU depending on how many tabs are opened (that is normal of course especially if with flash contents). What is not normal is that CPU will not be released when tabs are being closed, even with one (blank) tab left opened CPU usage is 40%-85% (depending if other process need CPU). Essentially: once Firefox process obtained 80% of CPU you can close tabs but you are fucked the same, now opening new tabs is a pain! Of course restart fix the issue. Is not a matter of addons or updates, Firefox and system (Windows 10) are updated to last version; I feel is something related with flash contents. Is it possible only me experience this?! Regards

Today I updated my Firefox Developer Edition to version 89.0b2 and now I just can not look at this browser anymore, "Inspired new tab design" is taking too much space and now became largest and at the same time least information-dense panel in my entire desktop! I searched around the web for a bit in hopes that I will find a theme or an add-on that will revert this particular change but no luck. I really want to revert to old UI look (at least tabs bar), there should be default theme or option to get back to old style. After some investigation I found userChrome.css but don't really want to install it (maybe this is actually the way of doing this kind of styling). Please help me revert UI design to old one.

Hi there!

I have been having trouble with Firefox continuing to autoplay videos even with preferences set to "Block Audio and Video."

If I go to twitter.com or elsewhere Firefox will show that auto play is disabled, but videos will autoplay with no audio. I would just like to get this feature working as autoplaying videos are incredibly annoying!

Thanks for any help!

Hello, I am trying to return to using Firefox after many years away. I need to disable the shortcut keys but cannot find where or how to turn them off. This seems very odd as I am sure its a popular need, at least for certain keys let alone the complete set. As a disabled user I use a program called Phrase Express to fill in all sorts of things for me including online forms. However, firefox's shortcut keys are interferring with those of the much more useful Phrase Express. I am astonished that a simple answer was not easily available whilst searching other questions etc. However, many similar questions were many years out of date and lead me to various addons which were no longer active. This cannot be a difficult thing to do, after all many people (will never even use them and even programs developed my single progammers usually have a simple series of options available in settings to turn them on or off or indeed customise them.

So, can someone please help, the need to use phrase express is essential to cope with my neck and arm problems but I wish to leave Chrome and more importantly Google behind me.

Thank you in advance for your guidance and assistance.

Ever since IE changed to tabs on top firefox coders followed like mindless automatons without any regard to/for Mozilla community and users. We are sick and tired of being ignored. We want/need tabs bellow address bar. Now, tell us how to simply get tabs below address bar or tell the coders to provide us with the option. And, we don’t care about any excuses as previously provided or outright ignored by them.

I was running just "regular" Firefox on my Windows laptop. Yesterday my help desk had me upgrade to Firefox Extended Support Release to install a corporate email security certificate. I did not know when I installed this version of Firefox that it would overwrite my existing browser, and when it did, I lost all of my add-ins, extensions, bookmarks, etc. I'm hoping to be able to restore my old profile with all of the existing data I had. If I have to "downgrade" to regular Firefox I think that's fine since I just needed the ESR to install the security cert and that's complete now.

I looked on the about:profiles page and I have two other profiles, default and june19 (I presume the latter is from June 2019?), but I don't know how to determine which one is the preferred one. When I clicked Launch profile in new browser, it instructed me to create a new profile to protect my information and I hesitated to do that because I'm trying to restore an old profile, not create a new one. In case you can't tell, I'm not an advanced software user, so give instructions like you would to a 5-year-old or your grandma... lol. Thanks in advance!

Firefox has been saving images from some sites as webp instead of JPG for a long time. There have been repeated threads on this subject which get locked and then pushed into the long grass.

Sure, I could botch a solution by installing an add-on to convert them, or I could use something like XnView (which I do, periodically, and in bulk) after the save event has happened, or I can edit about:info to tell Firefox not to accept webp - but this breaks functionality for some sites (like eBay), but I have found that in the end I have had to start switching to Microsoft Edge to do my browsing for a number of sites because Mozilla Firefox are ignoring repeated user requests to provide a simple option to STOP doing this.

I don't want to save any files as webp - save them as PNG if you like, or jpg, but I use an ancient copy (v3.24) of ACDsee (from the days of Windows 98) for my image browsing, sorting, viewing etc because it is perfect, blisteringly quick, has no extra editing or other functionality which I don't need or want, and it doesn't bloat up anywhere with thumbnail files... but sadly webp didn't exist back then so it doesn't support it. I have used a number of much more up to date browser-viewers, but there is nothing can touch this OLD version of ACDsee for basically brilliant design.

I'm not changing my image viewer. It's non-negotiable.

I WILL however change my web browser if I have to, if the developers of the browser continually kick into the long grass to lock, hide away and pretend there's isn't an issue which has been repeatedly flagged as an annoyance for so many users.

I have been using one form or other of 'Mozilla' family of browsers since the days of Quarterdeck Mosaic. I don't particularly want to switch my loyalty, especially to Microsoft, but if they are listening to what customers want and providing it, and Mozilla are not, what else is there to do ?

I am a retired systems developer. I cannot envisage this being SUCH a big ask.

Modern software treats its users like idiots and takes away control, doing everything it's assumes on their behalf that they will want.

It is not difficult to provide an option within settings for when saving webp files to save as webp, png or jpg with conversion if necessary. All you need to do is hear the screams and respond. :)
