I updated my desktop browser today and now there is an expandable sidebar at the left margin of the window showing tool icons for Tabs from other devices, History and Customize sidebar. I can see how to remove tool icons and how to expand or collapse sidebar but can I remove the sidebar completely? Is this an option? I prefer the old look with the browser web page content extending all the way to the left of the screen, without the narrow vertical sidebar.

A sidebar has appeared out of nowhere. I removed all extension on that sidebar and it still doesn't go away. I already have a bookmark bar and extensions at the top bar. I don't want another sidebar at every firefox window. How do I remove the sidebar, please.

Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

Out of nowhere I got the sidebar today. An absolutely useless feature that I surely did not ask for. And there is no way of closing or removing it. Please provide a guide, to removing or hiding it PERMANENTLY!

I prefer the tabs be below the bookmark bar, and successfully modified the CSS file to do this some time back. Now update 133 has once again pushed them up below the menu bar. What do I have to do to get them back where I want them this time? And why can't you just leave the tab location preference alone when doing updates?

Can someone please tell me how to disable the new Sidebar? It is interrupting all of my workflow on the screen and it is frustrating with all of the choice and customization options in Firefox, that there would be no way to disable it.

Well looks like they did it to us again. My tabs are back on top again and need to put them below where I am a lot of other users like our tabs!

Update: Codes working fine now for 133.0

Today when I launched the browser, a sidebar appeared. No matter what I tried, I can't remove it, it really gets in the way, I searched for information all over the Internet, but I still couldn't find any information. How can I remove the sidebar?

I am using a windows 10x64bit desktop and I want to find a 32 bit version of Firefox for my laptop which uses Windows 7 x32bit. I have tried the download for customising, ie set it for Win7/8 but the version which is downloaded reflects on the laptop that that version can only be used on a Win 10 computer. Please give me a link where I can find the 32 bit version of Firefox meant for Win 7. THANK YOU.

Yesterday I have updated tp macOS 15. Sine then I have trupuble displaying any webpages in Firefox 130. Th econnection just times out. Any other browser such as Brave, Safari, Home, Edge are still working as before teh update. How to fix this please?

Over the past few days (Oct. 18, 2024) the green Download button has been missing. When can we look forward to the fix? Have uninstalled & reinstalled twice. Thanks.

As of a few days ago whenever I start Firefox the window appears with the Bookmarks sidebar panel already opened. I click the "X" on the sidebar and it will close - until the next time I start Firefox. If I choose Menu->View->Sidebar->Bookmarks and uncheck it the panel will close - until the next time I start Firefox. No matter how the Bookmarks sidebar is closed, it will always reappear when Firefox is restarted. Even if I switch to some other sidebar, Bookmarks will replace it on startup.

I've searched about:config and found no setting which seems to control sidebar behavior on startup.

I assume this is the result of some recent update. Is there no longer a way to permanently disable the Bookmarks sidebar?

MacOS 12.7.5 Firefox 127.0 (64-bit)

For a long time I've used Firefox on Linux with multiple instances each with their own profile folder. Today when I try to run these instances with separate profile folders I get the following error:

> Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile.

Profiles are created like this:

firefox --new-instance --createprofile "PROFILENAME ~/.firefox-PROFILENAME"

They are run like this:

firefox --new-instance --profile "~/.firefox-PROFILENAME"

It seems something has broken with the instance isolation as this is now throwing an error. Additionally I run "createprofile" it doesn't seem to actually create the folder.

firefox setup 127.0.2.exe offline installer fails with message about "extraction failed" and popup "file is corrupt".

Windows explorer shows file properties and a signature for mozilla.

Is there a way to manually unpack the .exe? Someplace that issues are logged with more data (which file is corrupt?) There is a progress bar that flashes by part way, then a popup window with the file corrupt message.

(Trying to update to hopefully get rid of some crashes.)

Is there a hash for that .exe I could check?

How do I stop it from appearing please? It's the address bar.. field. I don't know what to call it, english is not my native language. I just want it to remain small and static like it always did. Now it becomes a huge field that takes up too much space and blocks my vision and I just want it to disappear.

I wish Firefox would stop changing stuff like this.

At some point Firefox stopped allowing me to drag tabs or bookmarks around. This includes moving tabs around in their order, dragging a tab into a new window, dragging tabs into bookmarks, moving bookmarks around in the browser. I can't drag them around in 'manage bookmarks' either. I can still open and create bookmarks; they are simply much more difficult to place where I want them.

I believe this happened with the last update but it's not a feature I use all that often so it could be older.

I have opened Firefox in safe mode and had the same issue. I have turned off the computer several times since this began.

Any help would be appreciated.

Hello,

I experience constant tab crashes a couple of days now. I tried safe-mode and re-installing the browser. But the crashes still persists. This only happens with firefox.

Been trying to identify the problem. Here are some crash reports. All of them have the signature (unloaded T_Prevent64.dll)

Mozilla added Accuweather to my New Tab page today. I can't use it because my VPN uses other locations. I attempted to remove it using the "solution" from another user's post 9 months ago. However, none of those things worked. There is no "Tools" option in the menu and I unchecked and blocked every item on the "Page Info" tab under the "Permissions" header. Zero result.

The Accuweather feed shows up in the upper left corner of the computer screen and does not have a "dismiss" option. I did notice that it has some entries in about:config. Is the solution to be found there?
