Hello, I am using Firefox on a new computer, and I have a bizarre problem that I never experienced on other computers. The 'recently closed tabs' and 'recently closed windows' options are disabled. They are grey, and I can't click them (see image). Also, the 'reopen closed tab' when you right-click one of the tabs is disabled (grey). I have tried to search everywhere why it can happen and found nothing. Any advice on how to enable this option? Thanks

Everytime I load Firefox the bookmarks sidebar is not shown.

Navigating thus View => Sidebar => Bookmarks I can bring it up. It will stay visible for the whole of my browser session. However, after I've closed this session and started another. the bookmark sidebar is missing again.

How can I make the bookmarks sidr be available all the time?

FF 127.0.2 OS Windows 11 Pro v 24H2 Build(26100.994).

As of today, DirecTV is no longer supporting Firefox for watching live streaming. They show the attached image. Brave works, too, btw (Chromium-based browser). Do you know why this is happening? Has Mozilla been in talks with DirecTV about this? I use this feature every day.

After auto update this error message came up and will not allow Firefox to open. Earlier in the day it had also updated ( not sure to what version) and was working fine. Laptop was then shut down and turned off for aprox. 1 hr. I then turned it back on and tried to open Firefox and it again asked to allow Firefox to make changes to my computer to which I clicked Yes. It then would not open and this error came up. error message Platform version 127.0.2 is not compatible with minVersion >=127.0.1 maxVersion <= 127.0.1

I need to create a pdf file to share with an agency in another country that does not have Firefox. I am unable to create a simple pdf - all of the files are automatically Firefox pdfs. All attempts to convert this file to a regular pdf have failed. Please help!

I have been using sandrawhitfield@comcast.net as user name for Firefox account. I want to delete that email because I'm leaving comcast ASAP. I read instruction that say add a new email name as a secondary account and then delete the primary one above. I entered whitfieldsandra@gmail.com. I got a message that said that account already exists. Since I didn't know that or remember any password for it, I entered whitfieldsandra@gmail.com and said "forgot password." I changed it Now Firefox won't let me in using the whitfieldsandra@gmail.com account. Would appreciate any help you can offer.

I installed a dev version of Firefox to test a plugin.

Then I uninstalled the dev version, but now none of my profiles on the regular version work...

Please help me, I really need my old browser history and cookies.

When I try to use one of my old profiles, I get "You've launched an older version of Firefox" and it tells me to either Create New Profile or Exit.

I read online that people add "-allow-downgrade" to the Windows shortcut, but this does nothing for me.

Thanks you and please help!

I had to do a new install of Windows 11 and logged back into Firefox and can't find my old bookmarks. I got to this point and don't know how to retrieve old bookmarks:

C:\Windows.old\Users\meljo\AppData\Roaming\Mozilla\Firefox\Profiles Please help me.

Thanks Mel

I recently switched from windows to Linux, and was using it for 3 months now. It was due to window recall Feature. But still i was using chrome as default and daily browser. I wanted to explore firefox, its great actually, except 2 things which might need me to switch back to chrome or brave.

1. it don't have fu**king Profile switch, I mean i use 11 Profiles On Chrome, most people still use 2-4 profiles, how can we move to a browser that dont support profiles. I know we can add profiles by "about:Profiles" I tried it. It worked but guess what? To switch profile i have to manually go to that page to launch it. So much time consuming and frustrating. Why not simply add a btn on profile pic like chrome to switch profiles?

2. Add-ons is good thing, but there should be a way to install things from chrome web store, i not found any.

If firefox can fix these two things firefox can simply grow back to 30+ % market share, but if not people will just test l;like me and go.

There was an update posted today. I ran the update this morning. Now Firefox will not open.

error platform version 127.0.1 not compatible with miniversion >= 127.0

                                                                                  miniversion <= 127.0

Running Windows 10 Version 10.0.19045 Build 19045 64 bit Should I remove and reload program?

OK, I have Firefox (Windows 10 AMD64, desktop) configured to delete history when I close it.

So, I see that regular webiste cookies are deleted.

But are the HSTS website "super cookies" deleted?

https://ipleak.com/articles/what-is-hsts-super-cookies What are HSTS Super cookies and why are they dangerous?

thanx.

why do i get a message that firefox has crashed. what has happened. i am not satified with firefox. it is very slow and sometimes crashes.

but the main question is: what can i do right now.

A friend informs me that Firefox settings > General > Browsing > Always show scrollbars has been removed in version 129.

This is alarming because I need that option for accessibility reasons.

Could you please check and, if necessary, reinstate this vital option?

Thank you!

I had the situation maybe a year ago. I use the Firefox profile manager.

I just updated to 127.02, and now not I'm getting this because for whatever reason, since the update, I am somehow on the beta channel, but only with this profile. I just opened two other profiles, and neither is on the beta channel, although i don't know what "Firefox is being updated by another instance" means.

I don't know if it's just a coincidence, but I'm also just noticing that a number of my addons settings have reverted to default.

When I used to take screenshots, they would be automatically named with the date, time, and part of the text captured regardless of language. A few days ago and with no reason I can discern, it now saves any non-English screenshots with something like this "Screenshot 2024-06-23 a[...].png" instead of "Screenshot 2024-06-22 at 08-02-28 Politics Policy Polit[...].png" (usual for English text and what I used to get with all languages).

Which means I have to manually rename screenshots. Does anyone know how I can fix this because I am working on a project with lots of screenshots for topics from different languages?
