Firefox Community Forum

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.

Recently Firefox has been randomly crashing the past 3 weeks multiple times, Is anyone else having this odd issue ? I'll be watching a stream or youtube video and bam out of no where the Browser goes black for like 20 or 30 seconds then crashes. I sent in about 3 crash reports and wondering if the Firefox team is aware of this issue.

Why is there no price tag icon for Review Checker in the search bar for Amazon and Walmart? (I am signed in to Mozilla, and I tried turning off all my adblockers and Privacy Badger.)

Thank you for your suggestions!

Hi everyone,

Prior to the release of Firefox Desktop 133.0, which I believe came out today on 11/26, I was using the profile switcher that was in the Firefox application menu. I had all my profiles created in about:profiles and I had browser.profiles.enabled set to true. This allowed me to easily switch between profiles by pressing the hamburger button in the top right. However, it is no longer appears for me after the latest Firefox update. I'm not exactly sure if I'm missing something, or if this was intended as I know the profile switcher was a work in progress feature.

This reddit post shows what the feature looked like. I will also attach the images.

If anyone would know why this no longer appears to be working, or how to fix it I would greatly appreciate it. I know I can just use about:profiles or some other alternative, but I found this to be the most convenient.
