Tabs for my website URL, once assigned to a now-deleted container, keep crashing. Deactivating "Container" add-on did not help. My URL opens fine on other computers, other browsers. It seems permanently contaminated by a bad container assignment. No other tabs crash. Help!

The player stops to work and I constantly have to restart firefox for it to work again. The videos stall after not using the computer or closing the computer and will not restart. It happens to all videos on all websites

I keep getting the attached message when I sign into my bank. This just started yesterday (9/4/24), but when I sign in with another browser I don't have a problem?

Dear Mozilla team, as a old fan from early days of Mozilla Firefox, Im quite dissapointed with the same issue I am facing with Firefox browser. Even I created my profile, which one you can check from which year has been created, even after I synchronised all my bookmars, passwords etc etc, still no data is restored. I formated my laptop last week and thought that this time, with syncronising I will save a lot of time buut veery dissapointed again. STILL I am not having back my 100+ login details saved on Firefox. Also tabs. Now, on my browser promts taht my account is all syncronised but still blanco browser, with not a single saved data!

I will appreciate your help to get back my data, as soon as possible.

Regards, Enis Jusufi

Recently when I move the mouse, the screen zooms in. The "command -" does not reset the screen. "View sZoom actual size" works, but I have to use it many times each time I use the computer. What is causing this? How can I fix it? It only started in the last couple of weeks.

I have logged in to Mozilla, and I was under the impression I would find my password, browsing history and bookmarks there just like it was on my old laptop, but alas not. Ibhave trie looking for a solution but can't find anythjing that helps me out. I have also changed the password just in case it was that but it wasn't. Any advise on this thanks. Would ghate to go back to Safari. I am using Apple M3 MacOs 13.5. Thanks Anna

Hello! I'm running the current version of Firefox, and my MacOS is also up to date: 14.2. I'm building a website in Squarespace. On that website, I have a PDF link that, when clicked, will open in a new browser window, with an option to download. I've set that up in SQSP settings, but clicking the link only allows a download. Squarespace Support and myself were able to open the PDF in a new window in Chrome and Safari. Is there a setting in Firefox or something else that I'm missing that will allow opening the PDF in a new browser window? Thanks! Michael

Since like 2 weeks, Firefox on my M1 MacBook keeps crashing. This is really annoying which is why I have to consider switching to Brave.

Does anyone have the same problem?

duplicate of /questions/1433030 thread.

I‘m somewhat uncertain: I downloaded the Firefox Installer from (I believe) Mozilla.org via Edge. When I tried to Upload the file to VirusTotal I got errors first and it only worked after restarting the laptop.

The file hadn‘t been analyzed so far (which surprised me), 1 out of 72 scanners claimed to have found a Trojan but what bothered me more was that according to VirusTotal the file was compiled in 2018 with Microsoft Visual C/C++ 12.00.8168. It was also somewhat smaller than the last Installer I downloaded (342kb vs. 390kb), although both should be version 18.05.

So I‘m a little concerned if the downloaded file is legitimate?

- Marquis has colonised my search page. - I used to be able to get rid of it temporarily by going into troubleshoot mode and going through that whole process twice - oddly, it never worked first time. - Now that doesn't work. - I can only get to my DuckDuckGo homepage via my bookmarks, which means I can't have more than one page open at a time. Firefox opens by default in Marquis. - I downloaded paid-for antivirus software with no results, so I'm reluctant to get anything else unless I'm sure it will work. - I notice that several people on this thread and elsewhere have reported this intrusion. - Does anyone know what to do about it??

I recently got a new Mac, running Ventura. When I did I lost the second toolbar that used to be in Firefox, the one that shows frequently used programs, like Google, Apple etc. Instructions say to click on Firefox and select Preferences, but there is no Preference under Firefox. I tried looking under Tools and got no where. What do I need to do?

Since my upgrade in Firefox my home page when I open it fills only half the screen. I can enlarge it but that's a pain in the rear. Every time I go out of Firefox and then return to the home page it is half the width of the computer screen. How do I get to make the full screen my default? Thanks Richard

I constantly used the auto fill for credit cards, but went to pay for something and it didn't auto fill so I went to settings and there is no auto fill section under privacy and security?? WTH??
