I am trying to migrate from a very old version of Firefox (v. 55) to the current one, but there is an app that is more helpful to me that all the other features combined. That is the "Tab Grouping" app that will not run in any version of FF higher than v. 55.

In my work, which often includes a tremendous amount of research, I need to be able to quickly go from one group of tabs to another. If I had to open all these sites manually, that would take the better part of the day and frankly I don't have near the mental capacity to remember the tremendous number of tabs. I have had a couple replies (Thanks!) to this question sometime back, but unfortunately none were even close in performance.

So, can anyone direct me to an app that will allow very quick movement from different sets of windows/tab groups (please see screen shots below)? Is there anyway that I can get this app to work in Legacy mode? I have several other old apps that work perfectly well in this mode.

Hi, Mozilla team I hope that you have a great day, straight to the point, my UI sometimes crashes or some components glitch or don't even work as it has to This is a video below slowed(I couldn't upload the video).

Is there any way to rotate between different screen sizes option using shortcuts keymaps which appear during "responsive design mode" is on. I found extensions which resizes whole browser & they helps. but it also causes developer tool to resize along with browser which hinders me to see different css properties. so i am looking for a way to rotate only screens.

"Responsive Design mode" is what turns on when we press ctrl+shift+m.

I Love using firefox more than Chrome. This is my go to browser.

On all sites where I need to login with my work account I get a tab crash when the browser redirects to https://login.microsoftonline.com/ac4b0eb0-811e-4ab0-acca-8a87079290dc/oauth2/v2.0/authorize?response_type=id_token&scope=user.read......

This is a recent failure (this week), that occured without any changes on my own account to Firefox developer version 121.0b2(64-bits)

I had to install google chrome to overcome this problem. Chrome has no issues with microsoft authentication.

Please solve as soon as possible, otherwise I will be switching to another browser.

Hi My government has enabled SafeSearch over our internet. we cant disable or turn it off.

we had a solution to disable it by changing DNS in our browsers to CloudFlare. but unfortunately, it's not working anymore, so the SafeSearch is back online again...

now, how can we disable it?

I just updated to Firefox 120, and tried the new GPC setting (Tell websites not to sell or share my data). I ran into a problem when I went to the Xfinity community forums (https://forums.xfinity.com/) . It causes a banner on top showing they recognize the setting. There is an "X" in the corner, and some text that says "Hide this banner", but they are not active. Plus, I cannot make a new post or do a general reply (that weird forum software has both local replies to a particular post and general replies to the general thread.)

Is this a bug in Firefox, or a bug in their forum software? I attached a picture of the message it gives.

When I try to log into my website - https://huppbrian.us/tsc-admin - with Firefox Developer 111.0b8 (64-bit), get the following error first time every time... Error: Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress. If I try again without making any changes, I'm able to log in fine. I've tried playing with the protections settings, but haven't found the magic pill to fix this yet.

Steps to reproduce:

1. Have Google as the default search engine.

2. Type a search string into the address bar.

3. The address bar briefly shows a URL for the Google Search results.

4. The address bar is very quickly overwritten with the original search string.

See screenshot for example.

How do I stop step #4 happening? I want the URL to remain in the address bar, for example to be able to give somebody a link which executes the google search.

I think this is new in FF121.

After a update my browser was running very slow, I'm not sure what I did but my whole browser, including history and bookmarks and add ons reverted back years. But I have a whole folder of Old Firefox Data which is from today.

How do I get this back on there and get everything back to normal?

In the pre-Webextension days, there was an add-on that allowed one-step install/run of downloaded executables. It worked like this: When the option was selected, the executable was downloaded into a temporary directory, execute it from there, and finally (optionally) delete it.

Now I only do it manually.

Ironically, MS Edge has this functionality built-in (see attachment).

Is there a way to achieve this on FF?

My chat sends garbage. Here I type 'test' to my son. Here is what my chat shows after I press RTN:

I am on Firefox Developer Edition 120.0b9 (64-bit macOS). Using sites like whatismyip and whatismyipaddress, I am seeing that I have a VPN or Proxy enabled. When I use Chrome, I don't see this. I went through all the settings and turned off anything that could even remotely be related, and still get the same results. Does Firefox have a built in VPN that I am unaware of? Is there a way to turn it off?

Noticed yesterday but not as prominent, firefox suddenly steals all window focus, trying to do anything in any other window is pushed into firefox no matter if it is minimised or in another workspace. I have tested this in a clean install along with a clean profile. Bitwarden and other windows seem to act weird when they are interacted with.

This all works well and good on b8 and stable. I am using wayland (Ubuntu 22.* default), but xwayland is available.

I keep getting signed out of my Google account whenever I close Firefox. I switched the Enhanced Tracking Protection to Standard, and I do not delete my cookies when I close Firefox. I even tried to disable the Purge Trackers option but this didn't help either. I have some dev-tools extensions installed + Adblock and Decentraleyes. It does not solve my problem if a disable them too. Would really appreciate anyone's insight.

as a a developer i use localhost often. However, a few weeks ago firefox started becoming very slow on localhost. I start a project and try to access it at localhost, but it takes a very long time to do the "initial load". then it works fast for a little while, and then its like it have to reload everything and that take a long time.

I have tried opening a private window to disable all my extensions, but without luck. I have tried checking my hosts file but found nothing wrong there. I have tried opening same localhost in Safari, but that works normally (fast).

I have checked online but found almost nothing, and the few things i found couldnt solve my issue. I hope there is a solution because this is a problem for me every day.

Every time I go to Fox News, the video at the top of the page drops to the lower right-hand corner. It's an annoyance I've been searching for a way to eliminate. I have pop-ups blocked in preferences and I have a couple of different pop-up blockers, but nothing seems to work. I'm currently using Firefox 114b.09 on a Mac Desktop.

I have a problem on YouTube where videos are too bright, but when i click for example to save that video to watch later it has normally saturated colors. And I'm using windows. On photo example1 video is too bright, but on example2 it is normal. thanks for help
