As above

Why would they disable accessibility tools without even a notice?

What kind of monsters would do that for the sake of political grandstanding?

TL;DR: Moved firefox browsers, didnt properly export passwords, uninstalled other browser, had logins.json from profile folder, needed to know how to import manually.

Fixed. I just installed the older browser, and properly exported the passwords this time.

My computer use to start up in Yahoo, now it starts in Google, and I have to open Yahoo from Google. How do I get it back to starting up in Yahoo?

Lost power. Computer shut down. Reopened Firefox and no passwords. Looked in profile and there are 4 files logins.json.corrupt (149 kb) all created today at same time and 1 file logins.json (2 kb). I ASSUME my passwords are in the 149KB json file? If I delete logins.json (2kb) and rename one of the 149KB to logins.json, when I reopen firefox, it just does it again: renames logins.json to logins.json.corrupt (149kb) and creates a new logins.json (2kb). Is there anyway to recover these passwords? Windows 7 Latest version of firefox

Thanx

Hello, once again the function of restoring recently closed windows has stopped working, it is displayed in gray and you cannot enter it I usually work on two or three windows at the same time and this function usually works, but I can't use it for the second or third time. Can I recover closed windows? I will be grateful for your help Best regards, Paweł U

Hi Mozilla,

The File System API is already available to all Chromium-based browsers, and also on Safari Tech Preview version. It is essential to create web apps for users. As seen on Mozilla documentation, many features of the API are already there, but these are not: window.showDirectoryPicker window.showOpenFilePicker window.showSaveFilePicker'

Will the full API set be available soon?

Best regards,

Dan

Hello! I have used Firefox on and off so I don't have a time frame of when this would have started exactly, but I have had some random completely black screens on both of my monitors dating back to at least 2-3 weeks ago that can only be fixed by powering down the entire PC. I've reinstalled my (NVIDIA) GPU drivers, rearranged display-port cables and just about anything before finally finding a fix, switching to edge. So far I've gone a week without black screening when with Firefox I'd get around 4 give or take a week (some days getting to 3 alone). I don't know what could cause it but I have noticed it only happens when first starting a video. Mostly YouTube but other video sites seem to have also caused it occasionally, I would just like to know what could be causing this, as I do prefer Firefox vastly and would like to switch back as soon as I can.

Will provide anything else as necessary!

For some reason the main texty font is OK in chrome but not in FF

Any ideas?

I have a problem with PDF showing.

If I take PDF generated by the lilypond and I open it from link like https://gitlab.com/lilypond/lilypond/uploads/f51162c65d5194db6dd3b4fb86fa4e42/bug.pdf, PDF looks well. If I open same PDF from disk by using link like file:///tmp/bug.pdf , PDF looks different (wrong). Some ledger lines missing.

I am running firefox 117.0 (64 bit) for Arch linux.

Recently, when I try to play a video on YouTube on Firefox, there is a flickering brightness effect (some aspects of the video seem to flicker bright and dark quickly) which is distracting and makes it difficult to watch anything. The effect persists even when launching in troubleshooting mode, and disabling hardware acceleration and restarting appears to have no effect. I have also been unsuccessful refreshing Firefox. Nevertheless, this issue is absent on Safari and Chrome when watching the same video.

Watching a solid colored video like this helps see the issue best, if it is happening to your device: https://www.youtube.com/watch?v=hJmFYZEcpZA The brightness switch is visible even when pausing the video.

When I find the same video two different places (ex: the Apple Sept 12 Event on Apple's site, versus on YouTube) only the YouTube video has the issue. However, I can't find any settings to change on YouTube to help this.

Ever since doing a refresh of FF two days ago, Yahoo mail doesn't work. I'm able to log in but contacts are missing and I cannot refresh the page without getting "The page isn’t redirecting properly." To log back in I have to either shut down FF (my settings are to clear cookies on shutdown) or clear cache or history every 5 minutes. I have not changed my extensions or other FF settings I had before the refresh. I have cleared cookies, cleared cache, added yahoo to the cookie exceptions list and nothing helps.

Thank you.

Hello ! ..I need help ! I accidentally refreshed Firefox, and now I cannot re-open all the tabs and the 2 windows I had prior to the refresh -- is there a way to get them back ?! I really woudl hate to have lost them all... Cheers

This problem started yesterday and I cant seem to fix it where youtube is too wide for my screen without any indicator on the top of my screen saying that its zoomed in and I cant watch any videos fullscreen. This glitch isn't a problem on any other websites. I tried opening and closing the browser, I tried restarting my computer tried clearing my cache and cookies and I tried using different accounts but none of them seem to fix the problem!

Photo 1: What it looks like right now Photo 2: What it should look like (had to use private tab) Photo 3: What search looks like Photo 4: What search should look like Photo 5: I cant see any videos fullscreen

All images, webm, gif etc. are loading, seemingly, exactly 20% upscaled compared to the real resolution of the media. I'm using a 4k TV (S95B), but I have desktop scaling at 100%, and browser scaling at 100%. I don't believe it's a GPU or OS system wide type setting because windows photo viewer gets pictures right. I'm using ShareX to measure the pixels of pictures. I can even load a local picture in a tab, and it will be upscaled beyond its native resolution. I have no idea why. I've tried a bunch of things, like setting layout.css.devPixelsPerPx to 1.0, which did nothing. I've reset Firefox to no avail, and I have noticed that Chrome is doing the same thing, which would usually indicate it could be the OS or GPU driver, but again, other apps load images perfectly normally. Do apps have categories on Windows now, where something like a "browser" can be told to treat media files differently than other media handling categories? I'm really lost at this point, nothing seems to work.
