Periodically I open Friefox and all my cookies have been deleted. I go into settings to find "Delete cookies and site data when Firefox is closed" has been checked (NOT BY ME!) again. This is very annoying as I then have to log into all my websites and go through 2FA. This is annoying to the point that I am posting on this site for help. Next step is find a new browser that doesn't screw up my work-flow randomly for no reason.

FF ver 140. just loaded and now all my sidebar bookmark fonts are black on black. How do I change the sidebar bookmark font back to white? When I disabled all Themes the white color came back, but enabling any theme and they the font turns black again.

I have recently re-installed Firefox version 140.0.2 (64 bit) following a crash and have been reconfiguring it to my requirements. I have the bookmarks drop down menu on the left of my screen but would really like it on the right hand side. I have searched the various on line articles but can only find a solution going back to 2019 which suggests that there is a small arrow next to the word Bookmarks at the top of the menu, but there is no such arrow on my version, only a X, which closes the drop down. I would have attached a screenshot, but the facility doesn't work on the drop down menu. :-)

Am I missing something here please or is this option no longer available?

Regards and TIA

I tried to use a ftp link setting firefox as the default ftp app, not realizing firefox no longer supports ftp. I am unable to reset the default app and can't find the setting to do so. I downloaded filezilla and wish to set it to be the default app for ftp. Can someone help me with this? Before anyone suggests it, resetting firefox to default settings is not an option.

I haven't figured out how to get Firefox to fill in Verification Codes when logging into web sites that require such.

Can you provide steps to this feature?

Hi there!

Is there a way to define the view in which pdf files are opened by default?

When I open a pdf file it opens in "Automatic Zoom." Is it possible to set pdf's to open in "page width" or a different zoom setting?

Kind regards

How to search for installed (both enabled and disabled) addons extensions in Firefox browser like chrome does via "chrome://extensions/" in 2025?

It is quite surprising that in 2024-25, firefox still doesnt have any option to search for installed addons via "about:addons". You can only search for addon site, not for those installed on your device and profile and browser.

Is firefox team really updating their browser for 2025 when compared to chrome?

In the previous version of Firefox I could install a multiple language keyboard layouts in the upper right row. I had to reset everything with a new HDD and Ubuntu 24, which comes with Firefox for Linux as well. Now I can't find how to install those shortcuts that I had before. I need to use Slovenian, Italian, Spanish, German and US keyboards (UK is standard with UK English as primary choice). Thank you for your help.

I've been using and enjoying Firefox for years on my various Windows machines. I've just purchased a Ubuntu Linux Thinkpad and have installed and used Firefox for a few days. It's generally working well except at start-up. Apparently it tries but can't restore the previous session, even though I have not selected "Open previous windows and tabs" ??

I am using lastest version on Windows and Linux (133.0) but I did notice the settings/options are a bit different in Linux, but I would just like to set my Linux FF to do same as Windows FF on startup, that is just two open tabs: - Gmail opened as a pinned tab. - Google Search as the open tab with focus I've attached a snip of the relevant section in General Settings How do I set this up in Linux? Thanks in advance

In Firefox on my Android phone, when I type about:config in the address bar and press Go, it takes me to a description of that functionality, not the configuration page. I have tried DuckDuckGo, Chrome, and Bing, and they all do the same thing. How can I go to the about:config page?

My Firefox version is 152.0.5 (Build #2016171143). My phone is a Galaxy A32 5G, model SM-A326U, Android version 13, One UI version is 5.1.

Does anyone know where Mozilla wallpapers are stored? I wanted to set a wallpaper from Mozilla's menu as the desktop wallpaper on my laptop. I looked for hidden files and checked the forums, but I can't find them in the given locations e.g. my profile. Maybe these files are masked somehow. I'm looking for particular wallpaper from the abstraction category (screenshot). Can anyone tell me how to find it?

Hi,

After the last two updates, the **Pseudo-elements** tab in the Browser Console can no longer be closed once it has been opened, and vice versa.

Please see the video below demonstrating the issue:

Thanks.

Out of nowhere I got the sidebar today. An absolutely useless feature that I surely did not ask for. And there is no way of closing or removing it. Please provide a guide, to removing or hiding it PERMANENTLY!

Currently, and for some reason there seems to have been a change that's occurred because my browser seems to think I'm out of the country (USA) as my searches return "We don't ship out of the country." How do I tell my browsers that I'm in the USA?

Just noticed the book mark banner under the URL line. It is taking up screen space. How do I get rid of it? How did it get displayed? Did some searching but no positive results. Not sure what to search for, definitely not book mark. If I delete the items from the banner are they deleted from my list of book marks. Some of these\book marks I do not remember saving? Where did they come from, some AI search or paid for vendor adds?

Using 148 on Debian trixie I do not see the option for "refresh browser"?

https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings

Does it still exist or is there an alternative ?

The newest version of Firefox now has what seems to be a permanent sidebar on the left side of the screen. This is incredibly inconvenient as 1) I have no need for it or any of the AI stuff and 2) I'm using an older screen that is square and so now web pages are contorted when I view them.

Please remove this bar or let me know how to remove it myself.

Thank you.
