Firefox Community Forum

Hi,

I have 2 machines (Win10 and Win11) with FF 140.3.1esr (32-bit) installed which demonstrates the same failure when I enter one site's url:

PR_CONNECT_RESET_ERROR

Chrome at the same machines goes at this url w/o any failures. Any ideas what to change on "about:config" in FF to allow it opening this url w/o such error?

I joined a Microsoft Teams meeting through Firefox on the web on a Linux machine. When I tried to share my entire screen, I was asked if I wanted to share the entire screen in a Firefox pop up which I said yes. Then the "you are sharing your entire screen" came up, the sharing icon was red and the "stop sharing" button was red. See attached image. This all disappeared and reverted to the default state almost instantly.

Teams has a feature to "manage what attendees see manage what attendees see" where the meeting host can preview shared content before making it live.

I am concerned that the meeting owner was able to see my entire shared screen without me even knowing it through this preview.

Can someone help? Microsoft just sends you around in circles and I can't contact Mozilla.

Hello Firefox team,

I did update my Mac to IOS 26.0.1 and I have lost all the history and bookmarks, I have the "Sync" enabled with my browser.

All my important data has been lost, can you please look into this and help me please.

Thanks, Sajeel Irkal

I filled out this form completely to resolve another issue only to come to the section at the lower part of this page. "Troubleshooting Information (optional): We can't automatically get your browser's troubleshooting data, please try these manual steps. "

I clicked the link...silly me...thinking the link would open a modal or popup. it took me to another page, losing everything i typed to ask to get a problem resolved. GGGRRRRRRRR! to put it lightly.

Maybe someone can fix that? I'm likely posting this in the wrong place. But it is posted and I hope the right people see it to not let it happen again.

Oddly, the browser kept the images for the form I was working on, only the typed text was lost.

Hello,

I'm facing an issue where my microphone does not work in Google Meet when using Firefox, even though I’ve granted all necessary permissions. This problem is specific to Firefox, as the microphone works perfectly fine in Google Chrome.

I prefer using Firefox because of its convenient screenshot features, but this microphone issue has caused major inconvenience during important meetings.

Kindly help me resolve this issue.

Thank you.

With FF 140.0 on both WIn10 and WIn11, new tabs opened automatically then closed after less than a second. Initially I thought this was due to malware, but on inspecting the History, I found the source of this annoying behavior:

// SidebarUtil.tab.js

// This is just a placeholder file to be loaded in a temporary tab to check if a sidebar is open and how wide it is.

Is there a way to STOP this sidebar checking with its tab opening/closing without disabling Java entirely ? Is this annoying behavior really necessary in FF ?

Version/OS: It happens across multiple Firefox versions, currently 140.3.1esr (64-bit) I should not use latest version because it is not recommended. On my Debian Linux 13 i recommended to install packages from a stable repository.

Issue: when i type some phrase into address bar to search for it, it opens a search engine homepage https://searx.rhscz.eu not search results page. I have added the SE to FF by visiting its search page, click address bar, empty it, click drop-down menu, select currently opened SE.

When I try the same search process using address bar for the second time and onward, then it opens search results page correctly. I think that this issue happens only on 1st search attempt since browser start.

Hello,

I'm writing because I’ve encountered an issue with the tab groups feature in Firefox.

Some time ago, after a browser update, I noticed a new feature that allowed me to group tabs thematically — I could name each group (e.g., "Study", "Work"), choose a color for it, and save and close groups to reopen them later. I found it very useful and used it a lot.

Last night, I decided to declutter my browser and closed several tab groups using the built-in menu. A bit later, I shut down my computer, but perhaps too quickly. This morning, when I turned my computer back on, Firefox was very slow to start. After a restart, everything seemed to work fine again, and the open tabs were restored.

However, all my previously saved (but temporarily closed) tab groups disappeared. In the tab group menu, I can now only see the ones currently open. I’ve searched through all the settings and history but cannot find any way to restore the missing groups.

Is there any way to recover the tab groups that I had previously saved and closed?

Thank you very much in advance!

Hello everyone,

Is there any software that allows software developers to see what the CSS they are creating is doing in real time ?

Because I can't imagine they're doing it blindly. I see some CSS files that have hundreds, possibly thousands, of lines.

If there is software that helps them see immediately what their CSS is doing, can it be used to create extensions (add-ons) for Firefox ?

Thank you for your attention.

Please change the switch in your code back to normal. Its just a tiny switch! normal is=task bar context menu by right clicking on the task bar WITHOUT "title bar". Is this so hard? And why is such important thing not fixed in 7 months?

I don't know what you're doing but EVERYTIME I do an update lately, something goes wrong. Today after update, my STGs are affected and ALL ARE GONE. I do NOT believe this is their fault. And you put this dang auto Startpage when launching window, I did NOT ask for that. I am so pissed, how do I get them all back? I had things I was working on that were very important. What else did you add to FF that I don't know about? I don't want your updates anymore. You screwed me big time. And I don't want the extensions YOU think I should have: Google, eBay, Bing, etc. wasting my space. I'm not the only one either, seen lots of complaints.

HOW DO I GET THOSE TABS BACK??????
