Is it possible to access Settings>Accessibility>WebsiteContrast to quickly turn it on and off, by setting it as a bookmark (or quick access) rather than having to click settings and search for it each time?

Can you let me know if this is possible, or possibly add it in a future update if it is not?

I know that there are extensions that allow you to do this, but I am wary of using too many extensions because they can be a privacy vulnerability.

Firefox keeps crashing I've followed all steps, still crashing - memory / disk/ system/restart/troubleshooting I did have animaze installed but removed and still crashing

Above is latest crash report

Firefox just updated to 152 this evening on my Windows 11 Pro system. It seems slow compared to prior versions. Also , every time you log out , it crashes and activates crashreporter which files the report. Any clues? Nothing changed on the system except for Firefox.

Since the Firefox update to 152.0 64bit I have noticed that it takes two attempts to log into Spectrum email. The first time I try I get a IDID-4000 error (see below image) after entering my sign on and password. I then have to retry by selecting the bookmark again and then after entering my sign on and password a second time I can get in. This does not happen in Edge browser. I have tried deleting my sign on and password in my saved passwords in Firefox and then manually reenter my sign on and password at the prompt for Spectrum and then saving it again but it keeps happening. I have also tried turning off enhanced tracking, clearing cookies and site data, refreshing Firefox and stopping my Norton 360 and it still happens. There must be a bug in the new Firefox update 152.0 that is effecting the ability to sign into Spectrum as this was not happening before. I am wondering if anyone else is seeing this problem and is there a solution to fix this. Should I file a Bug Report about this? We should not have to jump through hoops or do some work arounds to try and get things to work like before as I have read with other questions having problems with 152.0 update. This update needs to be fixed.

Respectfully,

I had a problem where FF 140.0 would not update, and in trying to get FF yo update, I used a re-install tool to which I was pointed in my problem report. This caused FF to wipe out my configuration, and I lost all my windows and tabs. I have gone to

    \Appdata\Roaming\Mozilla\Firefox\Proifiles\abnfpged.default

cleared all of the data therein, and restored that directory from a backup I made last Monday. But I cannot get FF to use that directory. "about:profiles" shows only two profiles, but the Profiles directory has five profiles:

03/10/2026 09:39 AM <DIR> qf00ka5x.default 03/10/2026 09:39 AM <DIR> v842ceue.default-release 04/11/2026 09:16 PM <DIR> .. 04/11/2026 09:16 PM <DIR> . 04/12/2026 03:08 PM <DIR> abnfpged.default 04/12/2026 06:29 PM <DIR> jdfj91sd.default-release-1775960183850 04/12/2026 06:48 PM <DIR> f1jq4mlq.default

Only the profiles beginning with "j" and "f1" are seen in the "about:profiles" screenshot I have attached. And I have attached a screenshot of my profiles.ini file. Also, in the abnfpged.default directory I restored, where is the list of all of my open windows and tabs? FF used to keep that in a sessionstore.jsonlz4 file, but that file is only written when FF closes. I tried to save a copy when I was having problems, but I stored the copy in the same directory, which FF changed during the re-install process. Here is my profiles,.ini file:

[Install308046B0AF4A39CB] Default=Profiles/jdfj91sd.default-release-1775960183850 Locked=1

[Profile1] Name=default IsRelative=1 Path=Profiles/f1jq4mlq.default

I have not worked with the ;profiles.ini file in many years, as my FF configuration has not had problems. Thanks.

Pressing the VPN button on my browser allows me to star or stop vpn o,k. but I would like to know how much I have used in the current month so I can be sure of saving some vpn for special sites e.g banking. I would appreciate tour guidance please

I realize there have been several questions on this topic, even with the same subject heading.

The popup generally appears if you're trying to exit or refresh a page but haven't hit post or submit after entering data into a field. It's a good warning in case you've forgotten to do just that. I accidentally restarted Firefox after an update, and when I returned to the site I was working on I got this popup. Which makes sense, because I had entered in a ton of data and hadn't submitted it.

However, the page that I was returned to wasn't the one into which I'd entered my data - it was more of a home page for the website. I suspect this is a lost cause, but ... is it at all possible that the browser actually has that data saved somewhere and is waiting for me to complete submitting it? Or is this just a false positive?

Since the Firefox Developer Edition update 152.0beta, saving as a PDF via the print menu no longer works. Although the “Save as PDF” option is available and selected by me, the job is always sent to the laser printer (which is not supposed to print it, of course). This happens on every conceivable website, so the website itself is not the cause. (Platform: macOS Tahoe 26.5.1)

For years, I’ve been able to generate PDFs via the print menu in FF without any issues—now I’m forced to take a detour via Safari, for example (which works correctly every time). So who has recently tinkered with this FF feature?

Since I can’t find the relevant setting in the FF preferences—and a “search” on this topic has been unsuccessful—I’d like to know if there’s a solution?

The latest update for the beta version 153.0b1 of 6/16/26 has made my theme stop working although it still says enabled. The theme is: ANIMATED Sakura by candelora 🌸 Theme Designed by candelora © 🌸 Animated Apng Theme I'm using Windows 11 on a Lenovo IdeaPad Flex with Firefox as my default browser. I'm an old lady, not tech-enabled in any way. Please help and thanks.

I am no longer able to open in Mac Preview or save when hitting Command + P, then 'print using system dialog'. It will only print instead. For instance, I save certain web pages as PDFs using the print dialog and now it will only print when trying to use either the save or preview options. Command + P, print using system dialog, then I choose either save as PDF or open in Mac Preview, but as soon as I do one of these it will only print. I am able to use save in the drop-down list of printers, but I need to be able to open in Mac Preview.

The release notes for Firefox 153 beta show a way to get the color picker.

Quickly pick and copy a color from any page by typing "pick color", "color picker", or "eyedropper" in the address bar and selecting the "Pick a color" quick action.

This does not work for me. Typing any of the proposals in the address bar just uses the normal search without showing the possibility to select the color picker.

Firefox is up to date, Windows 11.

I frequently watch BBC videos but approx one week ago, they stopped playing. I have your VPN which is usually off as it give me no advantage, (this appeared following the last update), but I've tried switching on and changing to UK location. No change.

Can you give me some suggestions please?

I have always been able to click on a box in the upper right to see my bookmarks on the left side of the screen.

This has now disappeared and the only way I can see the bookmarks is to go to "manage bookmarks". I don't see how to bring it back to the way it was.

I didn't knowingly change anything.

Thank you

Eliminating 40% from the zoom options was a change that seems quite unnecessary and is, moreover, extremely inconvenient! The previous zoom percentage options of ...80-70-60-50-40-30 were (more logical and) *far* more useful than the current options of 80-67-50-30. If for some reason you are limited to four values in this range, then I'd much prefer choices of 75-55-45-30 percent. The two images attached are saved at (resp.) 50%, which is too large for my purposes -- namely, inclusion as in-line e-mail images -- and 30%, which is too small.
