Firefox Community Forum

Is it possible to restore firefox to a previous version to recover all my data? After update, all my firefox pages, tabs, bookmarks and history have vanished. Please help me recover or restore. Thank you!

I have Firefox installed on three Windows Desktop Computers. On one, I just cannot delete Bookmarks, no matter what suggestions I try. Verify Integrity of the database produced no results. I do not, for a variety of reasons, sync bookmarks (or anything else) between the three installations. Experienced user that has spent far too long on what should be a simple issue.

I'm simply trying to email someone using the email link on their site.

The link is a mailto link which requires an email application (which I don't have). All I want is to copy the link to the clipboard.

Firefox lets me right click the link and copy the email address, but this doesn't allow me to provide the required Subject specified by the site's author.

I could have sworn Firefox used to have this feature. Netscape and IE certainly always had it back in the day.

I read online that Firefox is planning on implementing AI features. Given the track record of AI in other browsers leaking private information, bogging down connectivity, and generally being a nuisance towards users, I was wondering if there will be opt out features in future updates? Or know of forum threads that will update with tutorials on how to turn off AI features?

If not, does anyone on this forum have recommendations for no-ai browsers?

Dear Helper,

since the newest Firefox update, i got today (16.09.25), the audible cloudplayer doesnt work anymore, meaning it wont load the audiobook! I emptied the cache, but nothing changed. I tried the audible cloudplayer with Windows Edge and it works fine, so it is a Firefox specific problem. I granted all websides access to audio and media automatic replay, nothing changed. The cloudplayer doesnt work! So my question is: What else is interfering in Firefox with the loading of the player? Thank you so much in advance for your help :) Yours sincerely David

Firefox 139.0.1 (64-bit) on Windows 11

I occasionally increase the zoom level of websites (usually forums) with Ctrl+mouse wheel if the default text size is too small. However, if I forget to set them back to 100% (Ctrl+0) before closing the tab, the next time I open that URL, it's at the former adjusted zoom level -- not 100%. Really annoying.

How do I force Firefox to open all URLs at 100% regardless of the last custom zoom level? I have default zoom already set to 100% in Settings and Zoom Text Only is not enabled.

Thanks.

I had to do a new install of Windows 11 and logged back into Firefox and can't find my old bookmarks. I got to this point and don't know how to retrieve old bookmarks:

C:\Windows.old\Users\meljo\AppData\Roaming\Mozilla\Firefox\Profiles Please help me.

Thanks Mel

Hi,

Looking at my Firefox 147.0.1 settings for macOS 26.2 (Apple M1), I'm trying to adjust two settings:

-- I'd like to remove Languages -> English (GB) (its existence has odd side effects, like triggering United Airlines to offer fares in Pounds Sterling, and I'd prefer to just have English (US))

-- I'd like to disable Play Audio and Video for about:welcome (in regular and private windows)

I can see no way to accomplish this currently -- why?

Thanks.

Although I have successfully logged in many times, I get an error message today: An error occurred during a connection to b2clogin.firstenergycorp.com. PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR

When using Google Meet in Firefox browser, I am only able to share my window, not my screen. When I choose "share screen", it says I must change my permissions - but my permissions settings have not changed and this is a problem I have started having only in the last few days.

I do not know where I am supposed to change these permissions settings.

I have checked my permissions in settings > privacy & security > permissions - there is nothing there about screen sharing.

I have checked my permissions in padlock > connection > more information > permissions and the only options I have for screen sharing are "always ask" (default), which is set. The only other option I have is "block" which is not set.

My Firefox browser is up-to-date.

Can anyone help? Thanks!
