I run normal firefox on linux. Fully up-to-date. Every time I quit the app, it reverts to a version of my profile from a month ago, and loads all the tabs I had open then, and then receives all the tabs that I sent to the device in the interim (~1 month). As I speak, it just caught the 60 or 70 tabs in this window.

I tried changing the name of my profile folder to randomstring.defaultOLD and changed one of the backups to randomstring.default. This didn't change the behavior. I'm still stuck in the loop. I saved my tabs with onetab, because firefox isn't remembering my session anymore. I thought it was something to do with updates, like it only loses its mind upon updates, but that's not true. It thinks it's updating firefox EVERY TIME, because the one time it's loading to 1 month ago it was updating, but I'm 100% sure there are no updates to firefox in my linux. It's just hallucinating.

The articles on restoring from backup are outdated. They say to use an html file. There is no html file. It's just folders for profiles, not html files. HELP!

I've been using firefox for a little while- maybe three months now. I'm no expert on any of the config options. I run firefox using the built in VPN that my friend showed me how to enable, and I've been using it since. But now, as of roughly today, whenever I enable the VPN, no websites will load. At all. When I turn it off, they load instantly. But whenever I turn it on, it just gets stuck loading forever and ever, never actually getting anywhere. I tried enabling network.dns.disableIPv6 in the config page, because that's what I saw on a mozilla support page- nothing. Didn't do anything. The browser.ipprotection.enabled is still on, and I didn't change anything in settings. There was a firefox update very recently, but everything still worked with the VPN on. I just updated my computer, but I don't think that's it either because it wasn't loading things earlier today either. Not sure how to fix this. Please help?

My Firefox VPN is still showing as nearing my limit, despite it now being October everywhere in the world. Why hasn't it reset to 50GB? I've tried restarting Firefox and it didn't make any difference. It still shows "Getting close to your VPN limit. You have 2.2GB of 50GB left this month."

Albertsons grocery store states they support firefox. However I can't use firefox I have all sorts of issues so I have to close firefox and use chrome. What do I need to do to get firefox to work at their grocery store website?

Thank you Diana

Thank you. I’m not a technical person and so could you please share the specific and safe steps which will resolve both the error state shown, and the TLS logging issue without creating any other unintended consequences. I don’t want create any additional problems while trying to address these two issues. Thank you

HI All Recently purchased a laptop and want to have FF sync with my desk top. I am signed in to both devices with the same account and have checked all settings on both and they are identical. Why are they not syncing?

Hi, since the latest update, whenever I'm in a tab (e.g. email or personal website) and I go to upload files, all tabs show the last location of the last upload from any tab whereas previously they showed the location of the relevant tab. E.g. on a tab for my website it would previously open the location of my website files and if I switch to my email tab it would open the location of my email attachments. Now it doesn't seem to remember the loaction by individual tab it just starts in the location of the used loaction across all tabs.

Not sure if that makes sense, it's very annoying as I have to keep searching the location again between tabs.

Can this be changed back please so it remembers locations on a individual tab basis and not globally?

Thanks

FireFox Browser Crashing from Multiple Windows with Dual Monitors causing memory crashes in gnome.

google chrome used to have a brower extension called "The Great Suspender" to stop these crashes. If firefox can't figure this out I am not going to continue using firefox and go back to chrome.

Firefox tabs keep crashing for no apparent reason after this Nova update (its not website specific). here's a list of my top five Submitted Crash Reports (there are dozens more but ill keep this brief): Report ID Date Submitted

Hello,

I have had an issue for a few months now where certain websites fail to load. This is most easily reproduced on https://addons.mozilla.org, where I am shown the error "An unexpected error occurred" on most pages, preventing me from installing addons.

This issue does not occur in a Private Window, in Troubleshooting mode or in Chrome or Brave, but persists in fresh installs of Firefox. In troubleshooting this issue, I have removed all program files, registry data, and app data pertaining to Mozilla / Firefox. In fresh installs, I can sometimes install an add-on or two before this error starts occuring. I have not imported any previous data.

I was previously installing from Chocolatey, but in my last clean install, I downloaded from the official website.

I am on Windows 10 and Firefox 157. I use Proton VPN (Paid) and have tried changing servers several times to no avail. Again, this only happens in Firefox in a standard window, Private Mode and Troubleshooting Mode are fine.

Screenshot 1 shows the issue from my most recent reinstall. I was able to install 1 add-on (SponsorBlock) before it started showing up. Removing the add-on doesn't fix the issue. Trying to access addons.mozilla.org via a search engine results in the tab icon loading for a second and no change happening on screen (Screenshot 2).

I experience similar issues on other websites, like trying to log into Bandcamp.com (logging in gives the error "There was a network error. Please try again."), but most sites work.

Loading https://addons.mozilla.org/en-US/firefox/ gives the following results in the Network Console:

Uncaught (in promise) TypeError: can't access property "pressed", target is null

After a while bookmarks disappear from the browser tab and the only way to recover is to close the browser and open a new page that requires signing out of opened sites and starting over. Just started with new update release.

When I login to a site where there are many widgets (windows) on the screen - the windows are all missing scroll bars. If I login under a different browser they are there. This happened about a week or so ago. It has to be a setting change in Firefox. Please advise.

Ever since the last update, I can no longer watch recordings on xfinity stream with Firefox. What happened? Can I fix it? I sometimes have to start watching programs late, but they wont play while recording. I can watch those same recordings when they are finished, but not while they are still recording. I can watch those same recordings while recording on Chrome and Safari so it's not an xfinity problem. But for some reason not on Firefox anymore Is there a setting I need to change? Thanks Ron

Firefox just updated to 157.0 and will no longer open PDFs in a default viewer even when I change the settings. My setting say they are set to open in Mac Viewer, but continue to open in browser. I even tried to set it to open in Adobe still opens in my browser.

When searching inside a webpage the color of the item found hardly distinguishable with my theme. I tried to modify the ui.textSelectBackgroundAttention parameter of config. No results. The color stays the same old one.

This morning, I can no longer download (Save) files to my computer, nor check/change settings in Firefox. Tried all troubleshooting steps to no avail.

If I delete and reinstall Firefox, will I lose all my Bookmarks, etc.? Running version 157.0 (aarch64).

Appreciate any help!

Does FF have a maximum number of windows / tabs that can be open at one time? I use 12 workspaces each with multiple windows / tabs in them, roughly guessing ~100 windows and ~8-50 tabs per window

FF randomly hangs / crashes 1-3 times a day for me and has been for some time (over multiple revisions of FF; currently 157.0.1) requiring restarting FF

System: Large workstation, 128G memory, i9-7920x (12c / 24T) Linux, OpenSuSE Leap 15.6 FF source from FF repos, not OpenSuSE

Any settings I need to change to prevent the crashes?

Sorry if this is addressed elsewhere but I could not find it. After a recent update Firefox (Windows 11) started each website file download (mostly pdfs) at the Downloads folder. Previously, it would start at the most recent folder to which I downloaded a file. Since nearly all of my downloads are in a few neighboring folders way down the folder tree, I now have a ton of navigating to do for every single download. This is not sustainable. I have done a lot of Googling and investigated several suggested changes to about:config. I changed browser.download.folderList from 1 to 2. I made sure that browser.download.useDownloadDir is false. No effect. Any other suggestions? I am considering abandoning Firefox altogether. It has issues with some parts of the Medicare website. And an earlier update seemingly eliminated my ability to set a particular web page (Google) for new tabs, due to which I often wait a while for the page to appear, then realize I must click on Home. I like Firefox , but too many issues are accumulating and I can't seem to find solutions. Thanks for any help.
