I am using a number of extensions that were unexpectedly disabled when Firefox decided to update itself. The most important that "could not be verified for use in Firefox Developer Edition and has been disabled" is Mult-account containers. This is the second time I will have lost my data if I can't do so.
This being the second time I have to ask: Is this the fault of running "Developer Edition" and should I switch to normal FF at this point? Are containers not ready for prime time? Clearly something is wrong if I can loose all of my (container) data twice in a week.

Recently updated my 2012 MacBook Pro to macOS 10.15. After Firefox has been open for a while, it stops loading webpages. The title of the page loads, the browser window goes white and never displays anything; the page attempts to load continuously and navigation buttons don't respond. Other than that, Firefox operates and responds as though nothing's wrong. Meanwhile all other browsers can navigate the web just fine. Quitting Firefox (from the menu bar) causes the windows to close but an entry remains in "Force Quit" for an extended period. It can be forced closed from here, but doing so causes further attempts to open Firefox to have no windows appear; the only way to reopen Firefox appears to be to restart the whole computer. If allowed to close the rest of the way on its own- which can take up to 10 minutes- the crash dialog appears and Firefox can be restarted.
This has continued to happen despite repairing the drive, refreshing Firefox, removing and reinstalling Firefox, disabling hardware acceleration, running in safe mode, etc. There are no extensions installed and I have not synced my Firefox account.

I cloned the my FF profile from a well set-up computer A to a new computer B following the instructions at https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles . I gave the profile on comp. B a new name.
The operation seems to have been successful, except for the tab syncing feature. I don't see the tabs from both A and B in the synced tabs dialog. Instead, I see tabs open on the one or the other computer, or a combination thereof.
If I had to guess I would assume that each profile has a unique ID, invisible to the user but determinant for distinquishing devices (profiles).
If accurate: how to change that Id?

Hi, I would like to point out that the drag n drop feature of Firefox is not really good.
I have used many linux distribution and faced this problem from the day I started using Linux. I thought Firefox team would notice this, and work on this, so I didn't report any bug. But the problem stayed the same.
The Problem: When you try to drag a file from any file manager (I used Nautilus, Nemo, Thunar, Pcmanfm, and Dolphin file managers) on Linux, it will not instantly pop the "Drag files here" on supported websites. For example, when you try to upload files to mega, you have to drag and drop multiple times before getting it working. That doesn't happen with Chromium.
Even worse, if you try to drag and drop hundreds of files, Firefox will crash. I have also tried Firefox Nightly and Firefox Beta. Same. No improvement on them. Here I would like to attach a screenshot of the crash.

Hello,
I recently update to firefox 69 and now I have Firefox 70 and it's not usable at all. When I scroll Firefox blocks very often, it's the same for all websites. I need to click on the menu button and I see what I would have seen after scrolling. So if I want to scroll, I scroll, click menu. Then again I scroll, click menu button. After a few times, there is no more problem. it's like if the whole pages were in the cache at the end. And before there was to much information for the cpu.
When I write it's the same: it's not smooth, when I write an url, firefox stops very often for a second. The url is written at the end, but it's not displayed immediately.
Firefox don't crash, it blocks by scrolling and writing. When I click a tab or a button, it's responsive, no problem. I assume there is a problem, when it must refresh after writing or scrolling.
I'm on linux, I checked that graphic acceleration is enabled, no plugins. I tried to delete the directory ".mozilla" several times, start firefox in safe mode, but nothing helped.
Does somebody has an idea ?

Slow mouse scroll speed only on some websites while mouse wheel scroll works fine on others. Issue does not occur for same site on Chrome browser.

Issue: Mouse wheel scroll is slow for a few, specific websites.
Build: Firefox Developer Browser 70.0b10 (64-bit)
Description: When navigating to websites such as https://rogue.studio, the mouse scroll wheel scrolls the page very slowly. However, with no settings changed and using same browser instance in different tab, other web pages (such as support.mozilla.org) operate as expected with default mouse wheel scroll speed.
Environment: Firefox Developer Browser. 100% zoom. Resolution/Window Size: 1806 x 900px
Expected Behavior: Mouse wheel scroll has a consistent speed across all websites.
Attempted Fixes: Disabling Smooth Scrolling. Setting general.smoothScroll.msdPhysics.enabled to true.
Notes: I've noticed this behavior on heavily 'designed' sites such as https://rogue.studio. I'm not sure if there's a specific element or script that's causing the change/slow down for the mouse wheel scroll speed, but could be related as I've noticed this issue on this particular 'kind' of site.

On occasion if i close the window on laptop it'll only open main window on desktop on next boot. But this might only happen once and next boot the second window starts opening again for no reason. How do i make ff stop opening two windows on boot?

Suddenly Firefox hangs when navigated to next tab.
Also happens when Alt + tab to Firefox from other window.
Text is not typing in URL(address) bar of currently opened tab
Creating new tab button summons tabs, can drag tabs, but can't switch to any except one on which Firefox hanged.

I've lost all bookmarks, logins and saved passwords, add ons and basically everything. I have made sure that all my data is synced and even tested it a couple of times after changing devices and every time it worked perfectly and restored my data. Now, I've just changed devices after a while with no internet, I go to sign in and I forgot my pass so I reset it and signed in successfully but nothing at all is restored not a single thing. I'm devastated, I hope there a solution to this.

I was thinking whether editing and altering already cached earlier input strings could be possible. I know that the entire cache could just be deleted using "Clear Recent History". But that is not a well-planned option. Some input strings could have as well been simple typos or ill-formed strings. They could in fact be distractions or eyesores. So why not be allowed an option to edit the cached strings? I always do this for my .bash-history file to keep it compact and useful. So I figure there could be a file in firefox to do just that. Well, for a personal computer dedicated to a single user, this could be a good option.

Hello ! I'm using Firefox Developer (70.0b13, but happens on normal version too), and the Twitch streams lags when using resolution above 360p. When using the automatic quality, the stream starts at maximum quality. Then keeps dropping until 360p. Then the lag stops, but won't change back to max bandwidth possible quality. If I manually set the quality to 720 or 1080, the lag continues. Of course, I checked the internet and on another browsers (Brave and Edge Chromium). I can watch at 1080p without problems. I only have uBlock as extension installed. And this is happening for some time (more one week).
Any help is appreciated.

I was using a staging site and then went live and redirected the staging domain to the live domain. However, I then needed to re-instate the staging site. Now, whenever I go to the home page of the staging site, it redirects me to the live site. Any other page or url doesn't redirect. If I put a query parameter in the url, it doesn't redirect either.
