Firefox Support Forum

Im running Firefox on Apple Silicon and I really do wish that there was a way to change settings to adjust experience when using the browser. As for my current needs I wish there was a barebones mode I could enable because currently it's an energy hog and I am becoming discouraged to continue using it with this inefficiency.

Ill explain my use case, I do lots of research for school, and tend to work with 30-50 tabs at a time and by simply having Firefox open it drains my laptops' battery 3 to 4 X (times) faster. While the same tabs on Safari and even newly released DuckDuckGo Mac app can run those tabs for days while still sipping on battery.

another occassion is during my job search, these tabs will stay open for a week or two as I open jobs im applying to, using 'Skillsyncer' and bunch of gmail tabs. I prefer my laptop to lose 5% battery in 2 hrs instead od 3 minutes.

As things are now, Firefox is not well optimized and would like to let the Firefox team to add the mentioned functionality above. Sadly there's no way to reach out to their team and am instead forced to post here. For now I will refer to Firefox to 'Firefix' as there's plenty to fix.

Auto play blocking is no longer working.

media.autoplay.block-event.enabled true media.autoplay.blocking_policy 3 [tried 2] media.autoplay.default 5 [tried values]

Anyone have good values that block auto playing videos?

Hi, I've been using Firefox on all my devices for YEARS without any issues. However, as of recently, I had moved into a new apartment, and with that came a new internet connection, which was very slow since the beginning, but usable.

At first I had assumed that Firefox on my PC was loading websites more slowly because of my poor internet, which was partly the case - however, my laptop and Android phone were on the same network as the PC and were both much faster. So I assumed it had something to do with the differences between WiFi and Ethernet connections - the PC was plugged into the latter while the laptop and phone were using WiFi.

But then I noticed that Firefox was the only program with lacking speeds. Spotify loads video podcasts with no problem, Steam downloads are relatively fast (as much as my network allows), only Firefox took MINUTES to load a simple web site. For example, I tried opening Reddit on my PC to write this post, gave up, and am now writing it on my phone. The Reddit website is still loading on my PC as we speak.

I honestly don't know what could be causing this issue. I checked Task Manager, and Firefox isn't using any more resources than it normally would. I am also using the latest version, I just checked.

Any ideas or fixes? Even diagnosing the problem would go a long way.

‘Firefox froze while updating generating a XUL Runner Error Message "Error:Platorm version '121.0' is not compatible with minVersion>=120.0.1 maxVersion<+120.0.1’

I am having issues with Firefox crashing at various times though out the day. It always starts out fine, but at some point it just stops responding and I have to close the browser and reopen it. This happens at least once a day and it does it on different units (my LG Laptop, Dell Desktops (2 different units-1 at work and 1 at home), Surface Pro 9, my Dell laptop), so I know it is not the unit, it is something in Firefox! My Dell laptop runs Windows 10, all the others run Windows 11. Please look into this and provide a patch. Thank you!

PR_END_OF_FILE_ERROR how do I get rid of this error that keeps popping up when I attempt to launch Amazon.com I have never had this happen before..... it just started about a week ago.

Hi:

  I do genealogy and often have 20 or more WINDOWS (not tabs) open simultaneously.  I also rapidly type, copy/paste, between windows, etc. and can instantly detect slowdowns - especially irksome when the mouse disappears for seconds while the system is working.  I keep history and cookies...reminds me of pages I've already looked at when color change is enabled.
  After crashing a hard drive, I finally realized that Firefox was accessing the disk WAY too much.  Even with the system static (no page changes or updates), it was continually writing to disk.  Occasionally, it would take over the disk system for seconds.  Over time (years), as you guys improved, it became less significant; just broken up into lots and lots of small accesses.  Researched quite a bit...

  Started with increasing the sessionstore interval, but still was an issue.

To solve MOST of the problem, I saw a help note. I created and set to FALSE

browser.sessionstore.enabled

Plus modified several other sessionstore items This helped a lot...

   BUT this did NOT regulate sqlite storage for third-party stuff.

This is probably handled and hidden under another config section/ keyword (not called 'sessionstore', but '??thirdpartystore??' or what?) The following profile files are still handling a LOT of writes. I use Ancestry as example (the worst offender actually), but applies to other sites also.

.default-release\storage\default\https+++www.ancestry.com\ls\data.sqlite-journal ...
or occasionally
\https+++accounts.google.com ...

Just for these accesses, looking at 100k writes every second, like pulses. This is with only one window open and a static (no change) page. What changes on a genealogy page that requires updating every second = this is a list of dead people?? Finally, my question(s): What config sections and "keywords" handle these third party writes? Any clue/hint on how to eliminate?

Thanks

Last months problem with Firefox, one process goes to 11-20% cpu usage+-, firefox does not load sites, freezes, after some time works again. Tried every solution and nothing. I have to wait or restart Firefox. I have similar problem on Android and notebook from work. You are unable to fix your browser but you complain that that MS, Google and Apple block independent browsers. Maybe the way to fix is reinstall Windows. GO TO HELL!!!

Dear Mozilla

Long time user (love it) but the browser is consuming a lot of memory. With the same windows open in Chrome, Firefox is consuming 5 times the amount making the system slower glitchy.

This has been an issue for awhile and I checked all the posted solutions. Either the software is consuming an that is normal or something is running in the background. Firefox is at 1831.5 MB as I type this.

Can I uninstall then reinstall? or is everything going to return?

Thank you in advance

while using the site https://animesuge.to/home and using any server other than filemoon, the audio will either play for split second and then mute, or it wont play at all. The video itself plays fine. i tried it using other browsers and it works fine, it only happens while using firefox. i tried turning off all extensions and running in troubleshoot mode but neither of these helped.

I'm still using windows professional 7, it works for the most part. Unfortunately often the browser won't load or it will load and runs very slowly, then it shows a box saying close previous firefox. When it is running slowly I often have to hit the browser many times until the box shows up saying close previous firefox. Is this something to do with windows 7 or another completely different issue.

UbuntuStudio 22.04 uses the Firefox Snap package by default. The latest automatic update does not display pages correctly in normal mode, but does work correctly on Safe Mode. Snap.io lists only the latest version of Firefox so I was unable to ask snap to revert to the previous release (prior to 5 Mar 24) and by the time I had tried to investigate the previous version was no longer cached. I did not see a way to force a fresh download of firefox from the latest channel on snap.io.

I tried the snap beta channel for v124, but that exhibited the same problems.

I tried adding a symbolic link to colors.css after seeing firefox complaining that it could not be found when started from the command line. That removed the error/warning message but did not clear the problem with normal mode.

I use the en-GB locale extension only. The technical details about my PC are as follows:

• Operating System: Ubuntu Studio 22.04
• KDE Plasma Version: 5.24.7
• KDE Frameworks Version: 5.92.0
• Qt Version: 5.15.3
• Kernel Version: 6.5.0-25-lowlatency (64-bit)
• Graphics Platform: X11
• Processors: 12 × AMD Ryzen 5 7600 6-Core Processor
• Memory: 30.5 GiB of RAM
• Graphics Processor: RAPHAEL_MENDOCINO

I have now downloaded v123 and installed it in my local home directory, and that version is working well. I have removed the firefox channel via snap. It is likely to be a fault in the construction of the snap for v123 that was not present for v122 prior to 5 Mar 24.

Recently, in the past month or so, I have been having issues with my VPN addon Private Internet Access, my email provider Shortwave, and loading numerous websites. I tried troubleshooting it for a few weeks individually but it took a full Firefox refresh last week to get things working again. And it took only another week for everything to stop working again. The images in my emails are no longer loading (same issue as before), but they load in Gmail and I can download the emails properly, my VPN addon crashes and can't stay logged in same as before, and websites such as Nextdoor (I hate the drama but love the free goods) won't load the items for sale same as before.

I don't want to have to refresh every week, especially since I this is the computer I use for work and the amount of things I have to log back into is insane.

every time I check a like on tiktok a window pops up requiring to move a puzzle piece to where it fits in order for the like to register a real pain in the butt that should not be happening PS does not happen with chrome

I have just reinstalled windows and then Firefox. If I click settings then a menu item it just freezes.

I have uninstalled and reinstalled.

Using Windows 11 Pro 22H2.

Any suggestions?

Yesterday morning I opened my RBS online banking, without any problem. Late yesterday evening I tried repeatedly to open my RBS online banking without success. I would go through the usual log in process and end up with a blank screen. I tried a Firefox refresh which made no difference.
