why do my add-ons keep getting disabled?

ff keeps disabling add-ons that i have used for years and even keep a v. 5 to use the older add-ons and use the latest ff developer to use w/ more modern websites. ff even disables add-ons that worked perfectly well in ff developer and does not even give me the opportunity to re-enable them like i could before.

is there any way to force my old version to let ME decide what i want disabled/enabled?

I've had an ongoing issue with Firefox now for several months since upgrading to windows 11. When I try to copy text, or images, url's or anything really that is supposed to go to the clipboard, it copies a blank text with no data instead. I can copy text and images from other programs and even paste them into text fields on Firefox but I can't copy from Firefox to anything else and it's frustrating.

I recently got forced into upgrading Outlook in windows and hated it so I started using Thunderbird and surprisingly, I have the exact same issue there as well.

I have tried: Running Firefox in safe mode (Shift + Left Click) Resetting Firefox Switching Back to default themes Disabling hardware acceleration Updating to the latest Beta Build (v126) Running Firefox Developer edition

I really want to get this fixed and working, I don't want to have to switch to another browser =/.

Today when I close many tabs using control w firefox seems to randomly jump around when choosing which next tab to close

I wish to have firefox always close the adjacent tab to the tab I just closed

This should be the default behavior ... I do not see any setting for this ... is there an addon to do this ?

I am using the latest firefox on ubuntu

• • • UPDATE*** below answer for setting `browser.tabs.selectOwnerOnClose` has no impact on this

Hey folks, I use the firefox developer edition and I downloaded a zip file in it's private and when the download was complete I closed the window and open the download folder but the file was not there I haven't change the downloads folder location

I have had this problem for a while. I am not sure what to do so that I can fix this. Whenever I open a pdf or any application that can be opened in the browsers shows me two options for firefox browser. I attached a picture that will make it obvious what the problem is.

error text - " Firefox cannot verify application "

Hello! Can you help me sort out a little problem? I am reaching out to seek assistance with a specific issue I am encountering in the Firefox browser.

In my previous browser, when opening new tabs, they were considered active even if I did not immediately switch to them. This behavior allowed me to open multiple tabs, for example, by using the mouse wheel to open several videos from the main YouTube page. Subsequently, when closing the main page, the videos would be available in the order they were opened, facilitating a seamless viewing experience.

Upon transitioning to Firefox, I have attempted to configure the browser to replicate this behavior using the Sidebery extension. However, even with the extension, new tabs are not recognized as active unless I explicitly switch to them, making it challenging to maintain the desired tab activation order.

I have explored various settings and experimented with the Sidebery extension but have not been successful in achieving the desired result. In contrast, the Yandex browser, with the "Switch to the previous active tab when closing a tab" option enabled, behaves in the manner I am accustomed to.

Could you please provide guidance on how I can configure Firefox to consider new tabs active immediately upon opening, regardless of whether I switch to them immediately?

I added pictures to make it clearer what I'm talking about.

Thank you for your time and assistance.

Error Message: "Could'nt Sign You In: This Browser or APP May not be Sscure 1. Happened to Both Build 124 and 125 2. Virus Clean 3. Haved tried cleaning the cache and cookies

Firefox stop from 2 days ago read Google Recaptcha, from nothing.., Dev version to.. I have the last 126.0b8 and both not working, I try disable Tracking Protection and still, clean everything... spinning forever...

I try my Firefox at mobile, that works. I need Firefox working on this. Cant use Chrome...

Help!

I do not want my searches to be reflected in the address bar. I believe in prior versions of Firefox there was a checkbox to delete that provision. I'm using Firefox 123.0 64-bit with Windows 10 and have been through the setting and more tools areas but found no way to remove that function. I did try the about:config suggestions but still have no joy.

When watching a video on YouTube, the sound suddenly stopped playing. Currently, sounds in video and audio are not played on all sites.

The problem is only in the browser. Audio and video files are perfectly reproduced by the VLC player. There is also sound in the Chrome and Firefox ESR browser.

My actions. 1. Disabled all extensions 2. Clearing history and deleting all cookies

My browser - Firefox Developer edition, version 123.0b9 OS - Debian 12

P.S. I have been using the developer edition for many years. It seems to me more convenient and faster compared to regular Firefox. I really don’t want to delete the customized browser.

I need help with audio in browser...

Many thanks!

Changing the cookiebanners.service.mode to 2 in Firefox for Android beta via about:config is not permanent. After some time / Smartphone reboot / shutting down Firefox the setting is changed back to the default setting. -> how can I persist that setting?

I switched from windows 10 to 11 and to a new laptop. Here in my new laptop Asus tuf 15 ,even though it has better RAM , internet connection, cache memory, cores the FIREFOX doesnot function properly. It's extremly laggy specially when I use YOURUBE . In my earlier HP laptop with 8 GB ram I could use 10-15 tabs at one time .It would still not lag . It could do web development at the same time I could watch youtube tutorials. But now I barely open 4-5 tabs the youtube starts freezing up to the extent that I really get frustrated. Please so something or I will have to switch to BRAVE browser or something.

"Your browser is managed by your organization" suddenly appeared OS:Win11 Certificates: "ImportEnterpriseRoots" I've tried: Reinstalling Firefox Installing Firefox Developer Edition (it disapeared for few days but it was back) Deleting the registry key for it (after restart it appeared again)

 I have Avast and Malwarebytes but this has never happened to me before with this anti - virus

I am running Firefox Developer Edition (123.0b1) on Windows 11 and every time I start Firefox it maximises and then resizes to a set size with the maximise button set to restore size mode (I.e. the window thinks it is maximised). I have followed the steps detailed for this question: https://support.mozilla.org/en-US/questions/1411093 however that does not resolve my issue. This has only started recently after I turned the laptop into a tablet and back again. Once I "restore" the window and then I maximise the window it works as expected. However it is very annoying. Also if I start another instance of Firefox this new instance does not exhibit the same behavior.
