Could you make a shortcut to switch on between "dark mode" and "bright mode" in the mobile app browser + pc desktop browser?

There are enough webpages that don't show correctly in dark mode. It is not convenient to change the dark mode each time in settings!

Thank you

Hi folks, I restarted Firefox today on my Macbook and now the Restore Previous Session option is no longer working. I've tried the Sessionstore fix described here https://support.mozilla.org/en-US/kb/how-restore-browsing-session-backup but it is not doing the trick. I've used it multiple times in the past and it has always worked up until now.

I've since opened a couple of new tabs and then shut Firefox down to see if the Restore Previous Session will bring those particular tabs back. However the Restore previous session remains greyed out. I suspect it may be to do with the latest update to 149.0.2. I downloaded and installed that two days ago, but only restarted this morning so I think the update would have been done then. Are there known issues with this update, and is a fix coming? Thank you, Shane

I'm stuck in an endless loop in Firefox for Linux (MX Linux) whenever Cloudflare is used as security.

"Performing security verification

This website uses a security service to protect against malicious bots. This page is displayed while the website verifies you are not a bot."

I click "verify you are human" and it just loops back to the very same challenge. It isn't broken in other web browsers like Vivaldi for Linux. Or Firefox in Windows 11. Just Firefox for Linux.

It has been this way for months.

I recently refreshed my FF installation. Before I did that I had configured my tab settings to always display the x icon (close tab) in all active tabs. After the refresh, the x icon is gone for all tabs.

I cannot remember what I did to get them to display originally. I've tried to do this in the userchrome.css file. But it didn't work. Let me know if you have a solution.

Running Firefox in Kinoite - whenever I set a page to Reader view it is blank.

I have restarted in troubleshooting mode and it works, so I followed all the steps to try to identify what the problem is but nothing has worked.

I tried:

- Troubleshooting mode - worked - Disabling hardware acceleration - did not work - Disabled all extensions - did not work - Switched to default theme - did not work

Anyone any ideas?

TIA

Whenever I launch a YouTube video, It starts then the whole page freezes. No links work and no menus shows up when I click my mouse. I can do nothing to get the video to unfreeze. All I ca do is close the window.

As of today, every single time I try to download something, Firefox instantly cancels it and I'm not sure what the issue is. I've disabled adblock and Malwarebytes and refresh Firefox—same issue. Hitting retry from the download panel works but I can't figure out why the first download attempt is always cancelling, even if it's the same file. I'm not even downloading big files.

Two weeks ago I started getting popups telling me to use tab groups (pic below). I have no settings governing tab groups, I did not update Firefox, I didn't enable or change anything.

How to I turn this off?

Win10 140.8.0esr 64bit

How can i change bookmarks menu so it will close after choosing. Ive searched and only found option to stay open, (Option to not close menu when opening new tab)... Not what im wanting, I want to open bookmarks choose and have it auto close the side bar of bookmarks. Maybe even auto closing the link folders opened. Windows 11.

I recently switched operating systems from W11 to Linux (Zorin), and installed a new copy of Firefox. I rely on local web pages I have written for some of my work, but the new copy of Firefox does not find the file. For example, when accessing an image, e.g., file:///magrathea/dmpase/home/index/coastal24.png, Firefox gives the message:

File not found Firefox can’t connect to the server at local file What can you do about it? Check to make sure you’ve typed the website address correctly.

The address is correct, that is, the file resides at: /magrathea/dmpase/home/index/coastal24.png and the user does have permissions to read the file. I've tried adding up to five '/' characters to the beginning, and I have turned off all of my installed add-ons, but without success.

An apparently related problem is that double clicking on a '.htm' file also changes the address, for example, from '/home/dmpase/Desktop/index.htm' to 'file:///run/user/1000/doc/f07a8988/index.htm'

And finally, the "Brave" browser is able to read the files with no errors.

How do I fix this for Firefox?

I am not able to copy and paste in Firefox while using Microsoft Office for the web. I can in the same documents using Chrome & Edge I have searched the web and tried every setting I could find but can still not use copy and paste
