I'm at a loss for words here. I have a website I frequent and it has a really annoying behavior. I'm a developer so finally I mustered the strength to do something about it. I googled how to create an extension in Firefox and within 5 minutes I had a working extension that solved their annoyance. However, I can only load it temporarily. If I close Firefox, it goes away. When I try to actually install it, it says I need to have it signed. I have now spent the better part of an hour trying to find out how to self sign it. I refuse to believe that I have to submit this to Mozilla for me to be able to install my own code. Can someone please send me in the direction of how i self sign and install my own extension. I have no intention of publishing, I only want to run this for myself.

I've been having this reoccurring firefox bug every couple of months where randomly all audio from the application stops working is no longer available in the volume mixer of windows 11 (see example screenshot with twitch tab in background playing)

In the past, I was able to fix this issue by simply restarting the audisrv service and everything would work normally but now nothing I do seems to work. I've tried:

- Resetting - Uninstall/reinstall - Disabled all extensions - New profile

I do not have this issue on firefox dev or firefox nightly. If anyone has any ideas on how I could resolve or better diagnose this issue it would be much appreciated! TIA

Hi, Folks. When I open "manage bookmarks" (Library), why does it always open at "other bookmarks"? This is at the very bottom of the alphabetical list (and empty) so I always have to scroll back up to the top. I've got a lot of bookmarks, so this is extremely irritating. How do I change this? I've searched for an answer. The only likely solutions suggest removing the "other bookmarks" folder, but the description of how to do that doesn't work. Nowhere can I find a "remove other bookmarks" option. And the delete option is greyed out.

I don't necessarily need to hide or remove it, as long as I can get the bookmarks manager/Library to open at the top, ie. "Bookmarks Menu".

Cheers, Ian

When I go to website nypost.com, and select a random article that has a video display at the top of that page, a pop up of a smaller video window appears in the lower right corner of the screen.

For example,

Go to nypost.com Select an article with a video such as https://nypost.com/2024/01/30/metro/phony-uber-driver-charged-with-ripping-off-nyc-bar-patrons-in-cellphone-scheme/

There is a pop window of a smaller video screen that shows in the lower right corner

Autoplay is disabled

Is there a specific setting to stop this functionality of the pop up video window to appear? Is the block pop up window functionality in the same category of this description supplied above?

Thank you.

Firefox doesn't seem to have a built-in feature for listing the contents of each container tab in Firefox one at a time. That is, I would like to have only the contents of one tab container shown on my browser at a time, and be able to switch from one container to another freely. What is the use of containers if all their contents are displayed at once on the tabs of my browser?

Continuous 'Mozilla Crash Reports' from Firefox

I have a home-built media center (OS: Linux Mint 20.3) utilizing Firefox as the primary browser. This system has run almost flawlessly for many years. Updated to 20.3 in early 2022. Rather suddenly (yesterday) Firefox began repeatedly crashing, displaying 'Mozilla Crash Reports' (example attached). Firefox appears to initiate as expected. However, on display (e.g., Youtube, Facebook, web page, etc.) request, Firefox immediately throws a 'Mozilla Crash Report'. I do not recall any changes to the system that might have generated this condition, and have spend most of today unsuccessfully troubleshooting.

MB: Gigabyte F2A85XM-D3H CPU: AMD A-10 5800K APU with Radeon HD Graphics OS: Kernel: 5.4.0.170 generic x86_64bits; on 128MB SSD Firefox for Linux Mint mint-001 - 1.0 (122.0 (64 bit)) RAM: 7 GB

I have attempted to follow some of the moz://a Support pages (i.e., "Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems"). I have noted that while in 'Troubleshooting mode', Firefox appears to behave as expected, seeming to implicate extensions, themes and/or hardware acceleration. However, under normal Firefox operation enabling/disabling these does not seem to resolve the issue.

    * Hardware acceleration (on or off) still results in display of 'Mozilla Crash Report',
    * Default theme is selected, and
    * I don't appear to have any unaccounted extensions or other addons enabled.

Any thoughts and/or additional guidance would be greatly appreciated.

When I launch FF after rebooting an annoying ad pops up on the new page tab, the contents are:

'Get the inside scoop

See the add-ons our staff use to make browsing faster, safer, or just plain fun!'

It pops up just under the puzzle piece icon next to the address bar.

Is there a way to block it?

I set up a website for my wife a while ago. Most recently we noticed that some (not all) of our pages are not shown correctly when we use Firefox as browser. Specifically, when you open a webpage and scroll down as far as you can, there is a certain white area at the very bottom visible, below the footer. Now, if you wait a small amount of time, then scroll a little up and down again, the white border is not longer there and the page appears as it should.

Example pages for this behavior are: https://praxis-weinhold-schattentherapie.eu/entspannung/ https://praxis-weinhold-schattentherapie.eu/praxis/ https://praxis-weinhold-schattentherapie.eu/ueber-mich/

It is not happening e.g. with: https://praxis-weinhold-schattentherapie.eu/unterkuenfte-und-impressionen/ https://praxis-weinhold-schattentherapie.eu/angebote-und-kontakt/ Example screenshots are attached.

This strange behavior cannot be recognized with other browsers, we tried Chrome as well as Edge. Many thanks in advance for any ideas on how to adress this! Best regards Carsten

Is it possible to combine history/bookmark files? Firefox has truncated my "History" to 15 days and the only option I see to get elder entries is to combine a backupped history file with the current one. An easy-to-use tool for this task would be welcome. I did not change my config options after the update to 121.0.1 (64-Bit) (Windows 10pro) but I think I had the total history (from years) before the update. My current Options related to this topic are: browser.history_expire_days false places.history.expiration.max_pages false places.history.expiration.transient_current_max_pages 501234 privacy.clearOnShutdown.history false privacy.history.custom true history (*) Boolean Number String

I already sreened Help files of this Forum concerning lost history data but they all do not give sufficient answers or I do not understand them (as a German user). Thanks. Martin

  1. 1 I set the Manage Data tab to 'Allow' for sites I want cookies saved for. This sets the http and https addresses for the sites I enter.
  2. 2 I set the same sites in the 'Manage Exceptions' tab so that these sites do not have their cookies deleted.
  3. 3 Save Settings
  4. 4 Close and re-open Firefox. All cookies are deleted.

I suspect this is a bug?
