So I wanted to read PDFs trough firefox with a dark theme, looked up how to do so online, and people say to change the "about:config" option "pdfjs.viewerCssTheme" to "2" instead of "0", I did that, tried opening a PDF, nothing happend, it was still black text on white backgrounds. Tried closing firefox, reopened the pdf, nothing happened, still white backgrounds. Tried to check if it might have to do with that specific pdf file's config, created my own PDF file from a word document, tried to open it, still white backgrounds. Tried disabling extensions, (which I use four of, UBlock Origin, SponsporBlock, Return Youtube Dislike and Translate this page), didn't work. Tried enabling the option on my laptop, didn't work. Tried a bunch of other stuff and it still won't work. My Firefox version is 109 and I'm using Windows 10 I also don't want to use the console/file edit thing with grayscale(1) invertcolor(1) or whatever it was since it also reverses the colors of images instead of just the backgrounda nd text color.

After having to refresh Firefox, all extensions are missing from my toolbar. They're still installed and function but some require tweaking options on a per page basis and it's a hassle to have to work through multiple menus when they should just be a click away. From other answers, it seems like the extenstions should be in the customise toolbar page but only the standard options are there. I've tried disabling and enabling them, as well as removing and adding them again already with no results.

How do I either get them back to the toolbar or the customise page so I can add them myself?

I found a really unusual behavior.

If I close Firefox using the "x" at the top right of the window, the Windows default for close, it does not restore session no matter what I do. I can manually go to the settings, history, recently closed windows, and restore them from there, of course - but that is a definitive hassle.

Strangely, even if I open up a new tab less than 2 seconds before I hit the X to close, it will not restore the session but does indeed save the new tab to the previous.jsonlz4 file, and makes that available via going through the settings menu.

What is oddly more unusual is that if I close Firefox by way of ctrl-shift-q, it works fine (opening Firefox after ctrl-shift-q restores the session without any extra intervention required).

How do I make Firefox recognize closing via the bog-standard-since-windows-3.11-for-workgroups X in the top right of the window as properly closing/quitting?

When clicking on a link to an .mp4 file, Firefox navigates to a builtin video player, streaming the remote video file. When Firefox is unable to stream or display a file (as is the case with .mkv or .txt for example), it is downloaded instead.

I simply want .mp4 files to be downloaded when I navigate to them. I tried setting `media.mp4.enabled` to `false`, and that worked, but it also disabled most embedded media players.

Firefox v109.0.1 opensuse tumbleweed linux 6.1.12-1-default x86_64

I have been trying to get a "media print" to format as I wish it to do so by using the widows and orphans CSS rules (among others). So far, regardless of the values assigned, the resulting print output still has widows and orphans.

Are those rules actually implemented in Firefox?

i cannot print any web page from Firefox. The print option only offers me the option to save as PDF. Firefox is not detecting either my Brother laser printer or my Epson inkjet printer. if i use the print using system dialogue option fire fox shows a printer screen which has a simple entry of line prntr. If that is selected nothing at all happens. Clearly Firefox cannot detect my printers. If I save the web pages to a PDF file then open that file I can then get the normal system printing options and print the page. But all that does is clutter up my file system with files I will only ever use once. This proves the problem is clearly in Firefox and in its inability to detect system printers. I have tried all the suggestions from the help screens to no avail. Is there any other means of sorting this print problem.

Dear,

I need to recover my Mozilla (Firefox) account on my computer after this latter crashed. Unfortunately, apparently I don't have the good password. Probably I used an automatically generated password which I don't remember.

I still have my account connected on my Android smartphone, but I can't access the account details (no way to recover my password or change through this device?!), and I can't export my bookmarks. Also, apparently all my identifiers and passwords were not synced on my smartphone :-( Hence somewhere all my precious information are available, but stupidly enough I can't access it anymore and resetting the password warns me that I might (is it even a certainty or a possibility?) lose everything. It seems that I cannot even produce a revovery key (to reset pwd without losing data as mentioned in the Help pages) as I can't connect on a desktop browser anymore (but well on my Android version). I am lost and just stupidly blocked - this is SO frustrating, I initially thought it would be a good idea to put everything in Mozilla - well...

Is there ANY way to actually recover my account without losing data on my desktop Firefox, given I still have access to the email account associated to the Mozilla account (and to the original emails from the creation of my accounts) and I still have access to my Firefox account on the Android app but this one doesn't seem to allow to do anything interesting in my case??

Thanks a lot!

Hello,

There is a very long list of these that are associated with my account. I've imported my Firefox settings from computer to computer for at least twenty years. I may have made mistakes that caused me to pick up malware, and want to fix this, and some of these certificates have expired.

How do I know what to keep and what to either delete or edit trust regarding?

Is there any way to quickly and easily have all of them assessed at once?

Thanks very much!

Firefox has started making a piercing high-pitched screech when the "save image" and "file update" panels appear. This is a confirmation or alert sound I suppose. It occurs when saving an image from a right-click menu and when downloading a file. Formerly Firefox used the system default sound for this, and that sound is still working in other programs for similar operations.

How can I fix this? Or alternatively how can I disable the sound during such operations in Firefox (or alternatively system-wide)?

I've blocked Autoplay (Audio & Video) for *all* Web sites via the settings menu, but videos still continue to play automatically (abcnews.go.com, for instance).

I went to config:about, and made all the suggested changes I found in Mozilla support. Autoplay seems to be blocked now, but at the expense of Firefox going into an endless loop trying to load and play videos. While in this loop, Firefox is eating up 20% of my CPU sources, which comes to close to making my PC unusable.

I have Firefox 109.0.1, 64-bit.

This has been a chronic problem ever since I've used Firefox. Someone needs to take a MUCH deeper dive into why we can't block autoplay.

I recently had hard drive problems and during the ensuing melee, I discovered that Firefox has stored well over 100k files with the general name {xxx...}.final. Being the curious sort--and given that these boogers are taking up almost 1Gb--I looked at a few and they appear to be related to websites that I visited. I can see keeping some recent things around, but some of this goes back, literally, to the day I bought my PC. Um...that's a lot of files and a lot of space for places I visited once and will never go to again. Some of the websites no longer exist, so obviously those files are wasted space.

I am unable to find much about this on the web, either via Google or the help here. A few people have brought it up, but no one seems to know what to do. The help here goes nuts with the search term "final" and brings up a plethora of hits containing "finally" and so forth, but nothing useful. "}.final" isn't much help, either.

The path is C:\Users\<user name>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile name>\storage\default

Questions: 1) Can some or all of this be deleted? 2) Is there a way to tell Firefox not to be so anal about keeping so many useless things?

Given the sheer quantity of these things, it would make future backup/restores easier if I could trim some of the fat, but I don't want to mess things up, either.

Thanks...

So, for awhile now when I go to some sites, the screen suddenly starts flashing, then it jitters and turns some light color (like a light green; not blue screen, not black). If I guess where the "X" is to shut down the tab that has the video, I can end this. Often, like on youtube, I find the problem is some ad video that was playing. The rest of the site is ok. But not always.

One site I wrote down a few days where it happened: https://www.nbcsports.com/philadelphia/eagles/eagles-face-giants-2022-playoff-opener?cid=sm_npd_rsn_phi_fb_mn&fbclid=IwAR3rGUEa0W8fElrzCWANSIUpti9VKlbn0iHyvcFsviajYExo5tcRSyWBJXA

scroll down to video and everything blinks, becomes unuseable

It happens in lots of places, though. It is not per se a YouTube problem or just a problem at NBCSports. I shell out to MS Edge, and it seems to handle everything fine, so I'm assuming at this point it is a browser issue.

One last point: after this happen the screen display is degraded even after I manage to shut down the offending tab or video. It takes a Log off/log back in or reboot to fix everything. The degradation takes the form of making the screen look a bit like a pointilist painting, although that's an exaggeration.

FF 109.0.1 64 bit Windows 11 NVidia GeFORCE RTX 3060 running studio driver 526.98 (I have switched periodically from / to their gaming driver, which doesn't seem to matter)
