Firefox Community Forum

I have set Firefox to not automatically restore the previous session on launch. That is, "Open previous windows and tabs" is unchecked in the Startupsettings.

Most of the time it does not do so, however the previous session will get erroneously auto-restored in the folowing circumstances.

Open a few tabs in a normal Firefox window. Fully quit Firefox (via, for example, pressing ctrl+shift+Q). Open a private window first. Open a normal window second.

What should happen is that the new normal window contains just a single new tab. What actually happens is that the tabs that were open in the previous session get auto-restored in this normal window.

To sum up, there is no auto-session restore if Firefox is launched with a normal window first. There is auto-session restore if Firefox is launched with a private window first, and then a normal window is opened second.

Is this a known issue, and are there any known fixes to prevent the auto-session restore in the latter case also?

After uninstall and reinstall my Firefox i can't restore my bookmark. I used (CTRL+shift+b) and restore my file "JSONLZ4". But i have an error as "Unable to process the backup file". I read your forum and test many things but nothing. I also used the https://www.jeffersonscher.com/ffu/bookbackreader.html,but it does not work? It prompts:failed JSON parsing: SyntaxError: Unexpected end of JSON input. I really need my bookmarks! How can I restore them?

Is it possible to click individual segments of an URL in the address bar to navigate there directly (without manually selecting and deleting the tail)? It's a convenient way to reach upper layers of a website.

For example Vivaldi implements it via Ctrl+<Mouseover/click> (see attached screen capture)

Is there an option or addon to enable this? Thanks in advance

I'm really shocked that the developers at Firefox has not at all fixed the memory leak issue, which caused my PC to crash three times in a row. This is clearly unacceptable; even other browsers I use don't eat up a lot of RAM in a matter of seconds that ends up my PC lagging, or worse, crashing as a result. To the Firefox devs; why are you overlooking an ongoing issue that should've been easily fixed from the get-go, especially with updates that obviously have nothing to do with the memory leak issue? It's really easy to make such a popular browser not hog up memory so easily without causing so much lag, even on higher end PCs.

If the memory leak issue isn't fully resolved by greatly reducing memory usage, especially if I'm only using one or two tabs with me, I will have to consider seeking for another working browser that does not have a memory leak issue, and remove Firefox and never reinstall it altogether.

How do I remove or permanently hide the sidebar? It is currently taking up too much of my screen space and I can already access my bookmarks without needing them to be accessible on the side. Please make a user friendly version that allows people to easily remove the sidebar. Customizing so that it still stays there is not helping.

Hi,

I have a sidebar that appears to be permanent and I cannot make it go away.

I opened firefox, went to reopen the previous session tab with control + shift + t, and my fingers slipped and hit the wrong combo of buttons.

Then this thing appeared. This sidebar. I looked for similar questions on the topic, but it is not the history or bookmarks sidebar that pops up from control + h or control + b. I love hotkeys.

So my question is, how do I disable the dang thing?? I tried going into custom tools, I tried looking into settings, but I really cannot find this. And it seems that other issues are usually to due with bookmarks/history sidebars - which I don't believe to be the issue here..

Any help is greatly appreciated!

It's the sidebar on the left in my image if that provides any further info!

Thanks :)

Firefox now asks for primary password every time it starts even if it is not needed to access a site with a saved password. Removing and resetting primary password does not fix the problem.

Even though my laptop, tablet, phone and PC have the language settings set to English (GB) my Firefox across all platforms has changed from displaying English results to displaying results in French. I have gone through and changed all my language settings in and outside of the browser from English (Canada), to English (GB) to no avail. It still shows up in French. and I have had an French to English translator popping up when searching in Firefox. I can't see anywhere else to change the language. Everywhere I see, it says English (GB), but still displays French headings to the searchs. Any help will be great. Thanks.

Hi everyone,

Prior to the release of Firefox Desktop 133.0, which I believe came out today on 11/26, I was using the profile switcher that was in the Firefox application menu. I had all my profiles created in about:profiles and I had browser.profiles.enabled set to true. This allowed me to easily switch between profiles by pressing the hamburger button in the top right. However, it is no longer appears for me after the latest Firefox update. I'm not exactly sure if I'm missing something, or if this was intended as I know the profile switcher was a work in progress feature.

This reddit post shows what the feature looked like. I will also attach the images.

If anyone would know why this no longer appears to be working, or how to fix it I would greatly appreciate it. I know I can just use about:profiles or some other alternative, but I found this to be the most convenient.

How do I remove the sidebar permanently. It is now as I said above about 2.5cm wide and growing! I want it gone and none of the solutions give any idea how to do this. The show/hide button only made the damn thing expand!

I updated to version 133 today and was confronted with the vertical tab bar. I did not ask for this or want it, and now I can't get rid of the side bar, in fact I seem to have just made it worse / wider. How can I get rid of this (and block it) It is just taling up space on my screen. Please help.

I am so frustrated. Although I'm relatively computer literate, I cannot find a way to stop that sidebar from opening up on Firefox Browser 133.0. I'm using Windows 11 Pro. I can find no button that allows me to either delete it or prevent it from opening. For heavens sake, not everyone wants all this stuff. I just want a great browser with minimal things to have to deal with. It is irritating to have to deal with this when there appears to be no simple solution to get rid of it. I do not feel comfortable with having to try to delete a profile element. Just give me the button to say I don't want it showing up when I open Firefox on my computer. It can't be that difficult. I use the menu bar at the top of the page to deal with bookmarks. I don't need a sidebar. Give me the option to get rid of it. It will always be there to hit the button on again if I choose to but I know I never will. It interferes with my page. If it isn't fixing something that is broken, and you want to try new things, fine. But give me the option to delete it from my experience.

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.

Hello,

I'm receiving the following errors on my Firefox browser: Procedure entry point & couln't load XPCOM. I still have the old icon on my laptop, but I downloaded a new icon/app, and it doesn't have any of my passwords or favorite pages. Is there any way to access my old Firefox browser?

Thank you

Previously asked this question but didn't receive any Mozilla support. All they replied with was "we really only help with account or VPN issues now."

How is someone supposed to get a bug taken care of?

Since update to version 132, the primary password box keeps popping up, randomly, even after I put in the password. Only started happening after update to 132.

Can someone from Mozilla actually look into this?
