Firefox Support Forum

When I logged onto Firefox this morning it asked me to update which I did. When I got onto Firefox all my tabs were gone. Please tell me if I did something to cause this and how to keep this from happening again. I do have it set up to restore tabs when logged off and starting up again. Also please tell me how to get my tabs back! I tried to follow instructions for this but actually didn't have the things they said to click on. Thanks so much for your help!!

Hi Firefox team

I am Yuki belong to Electronic company IT department. We have a project to implement salesforce for customer facing and target to go live by end of this July. we are facing one issue related with firefox and salesforce.

<issue detail> Our salesforce have customized serach founctions. this search function doesn't work only in firefox browser(Edge, Chorme is ok). we can send input data from salesforce to search, however search result doesn't appear.

<current situation> we were investigating this issue with salesforce. we found this article : https://developer.salesforce.com/docs/platform/lwc/guide/security-lwsec-async.html >When LWS is enabled, JavaScript async functions that are used from a static resource work in Chromium-based browsers, but don't work in Firefox currently. The issue is a bug in Firefox.

<requet to firefox team> Would you solve above bug?

if yes, I would like to know the timeline
if no, I would like to know the reason why you don't solve.

I am getting like 10 crashed tabs per day. I have been using firefox for years and about to dump it... I have brave, chrome and others on my computer and getting ready to dump FF. You need to figure this crap out. If its broke, I dont need it.

YouTube has been so slow in Firefox. It just takes a ton of time for the video to actually play. It's just a spinning circle in a video. I can refresh several times and then it plays. I cleared my cache, history, data...etc everything from Firefox. That seemed to help for a bit. Then it just resulted back to being slow. It's just in Firefox. I played videos in Edge. It was fine. No issues. It's just FireFox. It started most recently too. It wasn't happening a week ago. I even tried going back to an old version of Firefox. Didn't help. Anyone know how to fix? Not using ad blockers either FYI. I just want videos to play normally and fast.

One of the add-in permissions is "Access your data for sites in the “named” domain". I looked at that and thought, "That certainly cannot include passwords"; BUT the explanation for this permission is: "The extension could read the content of web pages you visit in the specified domain, as well as data you enter into those web pages, such as usernames and passwords. "

I was stunned.

That means that addins that get this permission have access to my banking/medical/etc. usernames & passwords. This is not acceptable. Can a permission be developed that would be: "Access your data for sites in the “named” domain" (except usernames/passwords).

The permission "Access your data for all websites" is significantly worse in that it applies to all sites.

Hi there,

Earlier today I had to do a complete software reset on my MacBook Pro (running Sonoma 14.5). Prior to the reset, I had been running the newest version of Firefox and was signed in; I assumed that Sync was on and that it was storing my passwords and bookmarks.

After the system reset, I re-installed Firefox and signed in again, but none of my passwords or bookmarks are showing up. However, under connected services, I still see the old (pre-reset) name of my MacBook Pro, in addition to the MacBook Pro's current name.

Is it possible to retrieve my pre-reset passwords and bookmarks?

I opened Tbird to see what version the new Ubu 24.04 installed (115.12.0, which I discovered wouldn't be published, so I downloaded v.r.2. In this set of FF (127.0.1) pages now, the mouse wheel will not scroll. It works everywhere else in my installation (24.04).

Ideas?

FF settings have "smooth scrolling" checked; unchecked it did nothing to improve. mouse is a ~recent Logitech (M317c) which as noted, works in all other apps.

thanks!

I tried to change the font-size of address bar, tabs, sidebar and toolbar using the method given in The method given in: [https://support.mozilla.org/en-US/que.../1239467] gives no change at all of the font-size no matter the value I use. Any ideas? I'm using Windows 10 Firefox 127

I have noticed in the help section that all sync data is removed if password is reset. I have just lost all my passwords, bookmarks, settings, everything, because I had to format my computer and didn't memorize my firefox password.

Is there any chance at all to have my data restored regardless? I understand I am at fault, but this outreach is my last hope, I guess.

Download Web plugin to access my Security DVR. When I type in the IP of the DVR, firefox will momentarily go to the plugin but then says it needs to be downloaded. HELP

Please close browser before plugin installation.

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

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 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 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.

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.
