Certain images are never created or loaded in my browser. Youtube thumbnails, for example, display as only light grey squares. I thought maybe my addons might be causing this, but the only one that seems capable is uBlock Origin, and I even disabled it completely. Anyone know what could cause this? Surely its a caching issue or something. I can include images if anyones curious.

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?

Any ideas why I am seeing these strange rectangles on Google maps?

Confirmed not caused by an extension as I still see them in Private window and do not see them when using Brave.

They don't stay in the same geographical location when zooming in and out.

Hello everyones,

My firefox on my ubuntu give me to "bug" :

first "The bookmarks and history system will not be functionnal..." second, when i try to sync sign up : "error 500"

What i have try, "rm -rf .mozilla .cache/mozilla" i have download latest version and execute "firefox-bin" i have try to chmod 777 all this folders and under folders...

i'm working on it from three hours and have read many solution on firefox support or others website, no one works...

So can you help me ?

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.

I have several profiles. They all have the same Chrome folder contents, but only some of them have the "chrome_debugger_profile" folder.

I'm guessing I must have generated it along the way while tweaking the Chrome folder contents?

Hello everyone,

to archieve some good old games, I use an special version of Firefox. Firefox (MyPal): 29.2.0, with Adobe Flash preinstalled, Disk-Cache

For most games it will suffice: After loading all content online, it will be available offline too. But... some audio/video files will be saved in memory cache - %temp%\mozilla-temp-files\*[random-auffix] - instead of in disk cache. After closing session they get deleted and after restart they are saved again, with another suffix.

Sample file: http://arcaneonlinegame.epizy.com/Arcane/frames_files/midi/Ophelia's Journal.mp3 that is shipped with http://arcaneonlinegame.epizy.com/Arcane/Arcane.htm

How can I tell Firefox to permanent save streamed audio/video files, like Firefox does with everything else? In the end the music should play if I open the browser offline too.

Thank you in advance for your help. Drago

Hello!

I recently got a new computer with Windows 11 freshly installed. I downloaded Firefox, went to take a screenshot, and the usual shortcut of Ctrl + Shift + S does not work. I can right click and Take a Screenshot, and I can use other Ctrl + Shift shortcuts, like Ctrl + Shift + T to reopen closed tabs. The only one that doesn't work is screenshots. I can also put Screenshots in my top row Toolbar and use it, just not the keyboard shortcut.

I refreshed Firefox, uninstalled and reinstalled Firefox, as well as checked the about:config extensions.screenshots.disabled preference. It has been set to false, so I have set it to true and false again hoping it would "reset" it but nothing. Thank you!

Is spell-checking done locally on my computer, or is it done on the Mozilla website? I just found out that the Chrome and Edge browsers send my typed message to the home office, and that is where the spell-checking is done. Can I assume that this process is done locally on my own computer with Firefox?

I've been paranoid about security for many years, and every little bit of info I can add to my personal well-being lets me sleep that much better at night.

I am currently 82 years of age and have been using Firefox since it first became available, just because of its advertised security features. Quite happy with it and hope it stays on top of my needs.

And I have the same question regarding Thunderbird and its security properties.

Thank you.

Firefox 117.0.1 (64 bit) Build 20230912013654 Windows 10 Home - Version 22H2 OS build 19045.3448 The link to download my Sears credit card statement in pdf form has disappeared when accessing the website (https://citiretailservices.citibankonline.com) with Firefox. It still appears and works normally when the website is accessed with Chrome. I have the uBlock Origin extension installed on Firefox, but it is disabled on the Sears website. Screencaps attached.

I've been having an issue for a while now where the cloudflare challenges that ask you to click the check mark to "verify your connection is secure" would just endlessly ask me to click the button and never continue. Sometimes it would say to unblock access to challenges.cloudflare.com.

But if I a launch an incognito window I can visit website with the challenge and it won't even ask! I've added all my extensions to run in incognito mode and everything still works, I can visit the websites in incognito just fine. So the one changing variable is incognito vs non-incognito.

I can have two windows open, one incognito and one not, and browse to the same website and the non-incog window will fail but the incog will just go to the site.

I thought incognito was supposed to only affect the session storage? Does it silently change other things to the running environment of the browser (about:config options, slightly different extension configs)?

Anyone know why this small change would suddenly allow cloudflare challenges to work?

I try to set up Firefox Sync on Firefox on a VM on Fedora. I enter my e-mail and password. Then I get the message (after retrying): "Email resent. Add accounts@firefox.com to your contacts to ensure a smooth delivery." However, I do not get the email with the confirmation code.

My email address has this format j@xxxxx.org

I am using FF on a Windows 11 desktop. When I try to log into familysearch.org using FF, Avast detects that I am being redirected to https://590-buk-726.mktoresp.com. I have used both Avast and FF for years, and this is the first time this has happened. FamilySearch is a very legitimate genealogy site. I contacted Avast and they refreshed FF, and I was able to log in ok, but when I tried it again I got the same warning. I cleared all cookies - same problem. I deleted FF and re-installed - same problem. I am not getting this warning when I use MS Edge. Has anyone seen anything like this? What should I do? Thanks, Mike

I have been having this issue for such a long time now but its really getting ridiculous now, I have tried to follow so many guides and re-installs and .XPI installs and nothing is working, I am beyond stumped as to what can be the problem, someone please help me fix this.

Which file/s contains only the browser settings, not including the extensions, which are transferable to other profiles? prefs.js? the contents of the settings folder?

Everything was working fine on Firefox up until a couple weeks ago when my searches started lagging.

What happens is - if I type a search into the main URL/search bar on the browser, it loads just fine. But if I type a 2nd search into a website search bar, such as on google.com, there is about a 12 second delay between me hitting enter and the page actually starting to load. The page freezes during this time and is unable to be interacted with. This issue does not happen in any other browsers outside of Firefox.

Things I've tried so far: Troubleshoot mode/safe mode, clearing cookies and cache, uninstalling and re-installing Firefox

Nothing has helped... wondering if this was caused by an update?

continue in /questions/1424778 in Thunderbird section.

Having used Thunderbird for some time, I installed it on a new PC, and found that virtually all my emails on a particular account seem to have been deleted, despite the app being set up to retain them. I checked on the webmail (BT) and they have gone. The account is set up as IMAP - as is another account on the same server, which seems OK. BT won't engage with me on this as they "don't support third party apps" I assume that 3 years worth of important client history is gone for ever? Can anyone suggest what I did wrong, or is this a software failure?

Recently I activated 2FA on Firefox. I scanned the barcode by Google authenticator, to make it my code generator.

I'm now trying to enter Firefox on my laptop. After typing my password, when I try to enter one of the generated Google Authenticator codes, I constantly get a response "Invalid code".

I had to use one of the backup codes (out of the 8), and managed to enter my account on the laptop, but none of the logins and passwords were found there (it's empty).

My first question is why does Firefox reject the codes received from Google Authenticator (do I have to cancel my 2FA and define it once again? but I did everything by the book, with GA, and it seemed fine the other day).

My second question: I finally managed to enter my account with one of the eight backup code. Why are there no passwords etc? Aren't they automatically drawn from my usual (existing) account?

The laptop runs Win 10. I installed the 2FA on my main computer, which runs Win 11.

Thank you very much in advance, Eldad
