I met the same issue with https://stackoverflow.com/questions/27514404/web-worker-blocked-by-main-thread-in-chrome . It was asked 10 years ago and I learnt that it was fixed in chrome via https://issues.chromium.org/issues/40398809 . Is it a bug for firefox? Is there any way to work around? Thanks.

For the past month or two, at random times when I open Firefox, I see a message stating, "Looks like you reinstalled Firefox." To be clear I have not uninstalled Firefox in any instance where this message has been displayed.

When this happens, I’m unable to browse the web. To resolve the issue, I have to remove the uBlock Origin extension and reinstall it. Once I’ve done that, browsing returns to normal. However, I then need to reconfigure my filters and adjust settings within FireFox

I’ve tried uninstalling and reinstalling Firefox to see if that would prevent this issue, but it hasn’t worked.

This problem is specific to my PC—it has never occurred on my MacBook.

Any assistance in understanding why this happens and how to prevent it would be greatly appreciated.

Thank you.

Several weeks ago, I was attempting to upgrade from Windows 10 to Windows 11. In the process, I deleted Firefox (using Revo Uninstaller) and then reinstalled it, downloading it from the Mozilla website. Unfortunately, it didn’t run, giving me, at different attempts, different error messages. In the time since then, I have read many suggestions from many different websites and I have tried some of these suggestions, all with no success – until today. I have just completed the suggestions made on https://support.mozilla.org/en-US/questions/1327628 and Firefox is now back, working. I am happy and grateful, but not finished. None of my personal data came with the currently functioning version of Firefox. Since the re-emergence of Firefox, I have been reading several websites dealing with copy, backup and restore of my Firefox profile. Right now, the path C:\Users\rsuth\AppData\Roaming\Mozilla\Firefox\Profiles\ shows 5 folders: Two of the folders show 11/11/24 as the date modified (probably the date of the download from Mozilla). The folder 0dppjrfa.default contains one file, times.json, dated 8/11/2020. The other folder, ru82tlj5.default-release, has 97 items, most dated 11/11/2024. The remaining three folders are all dated 12/2/24 (today, as I write this). One folder’s name ends .default, the second name ends .default-release, and the third name ends .default-release-thirteen digits. The question that I am asking here is what do I do next to, hopefully, bring back the personal date I had with Firefox before my updating to Windows 11. Should I delete the folders dated 12/2/24? What, if anything, is the significance of the folder whose name ends in 13 digits? I’m hoping someone will be able to tell me how to fix these Firefox problems. And if I can, then I hope to be able to do something similar to help me bring back Thunderbird as well. Thunderbird became unfunctioning at the same time as Firefox. Thank you.

Suddenly Firefox is downloading my downloads to google drive. Why? I want them in my download directory, but changing the options in Settings/General/Download makes no difference. It is set to ask where a file should go, but does not. It is set to ask whether to open or save a file and it does not!

How can I get google drive out of this and save them to my desktop again?

Hi Everyone,

ever since the latest Firefox update, the "read more" feature on LinkedIn pages (personal pages, not the feed) does not show up anymore, at least not for me - the feature allows you to expand the various subsections to read their full content.

I opened LinkedIn on Chrome and Edge to see if it is indeed a browser issue, and it's working fine over there. I also did some troubleshooting (refreshing, clearing cache), but to no avail.

Does anybody else have the same problem?

Thank you!

I have been using the Firefox browser for years on the exact same computer running windows 8.1 that isn't having any issues or problems. Over the last 6 months the browser has been crashing every single day regardless of utilizing every setting mentioned in the help articles, numerous "refreshes" (numerous times it also freezes during refresh) and numerous reinstalls have done nothing. Every single day the browser crashes and I have to restart it or my whole computer. This is my last attempt to figure out what's happening before I stop ever using it again.

Since updating Firefox I can no longer connect to known good sites without getting "Did Not Connect: Potential Security Issue".

This includes U.S. government sites! For instance, try connecting to https://covidtests.gov/ .

Why completely block access to the site? Why can't I make exceptions or tell Firefox to accept the risk and continue?

I recently switched from Linux to Windows and installed Firefox on my new system. I signed in with the same Firefox Account that I had used on Linux, but none of my bookmarks, shortcuts, or other data have synced. It feels like a fresh Firefox setup. Here’s what I’ve tried so far: 1. Confirmed that I signed in with the same Firefox Account. 2. Verified that Sync is enabled for bookmarks, history, and other items on Windows. 3. Triggered manual sync multiple times, but nothing has appeared. Is there any way to check if my bookmarks were stored on the Firefox servers, and if so, how can I retrieve them?

I've been having issues with Cross-Origin Request Blocked errors for a while now. I'm on Windows 11. I first noticed this issue when visiting YouTube. I would go to play a video and any video I tried to play would just load forever and never play. Then I noticed I was having the same issue on Facebook. The page would load but then a majority of the images wouldn't. I can use YouTube and Facebook just fine on Chrome. The reason for the error shows as "CORS request did not succeed". Initially I tried uninstalling all of my extensions. Then I completely uninstalled Firefox using Total Uninstall (for good measure). Nothing has worked. I'm not sure what changed that would cause these errors. Could this be a network issue? I've been having issues with certain sites on my Macbook Air as well (Chrome and Safari) but I thought maybe that was because it's pretty old and not supported by apple anymore.

I cannot use any FAQ's or topics for help because I will not remember them when I need to use them. I need to know how to download to a USB drive; step by step directions/instructions do not help me. Is there a solution? I would like to purchase sewing machine embroidery designs online and then download them to a USB drive to insert into my sewing machine in another building. Microsoft has been no help with this. Any help would be very much appreciated and thank you.
