Diễn đàn hỗ trợ Firefox

First got a msg box from Firefox that my W10 PC had crashed overnite - and I could report it. My PC was back up & looked normal - but when I accessed Firefox the PC crashed - then I got the above error & blue screen and could do nothing on the PC! I restarted again - as long as I DO NOT START FIREFOX - my PC is fine. Help pls! For what it's worth, I happened to open a lot of tabs in Firefox yesterday. Drivers are up-to-date. Vicki

I keep a lot of tabs open (~60) in any particular session - I find it's faster in this way to get back to a site.

About every six months or so, I lose *all* these tabs because of Firefox's inadequate session backup system. It only saves two or three total backups, some of which are completely out of date. But the worst scenario is when (1) some site pops up a new window; (2) I mistakenly close my main window before the new window; (3) I open this new saved window once or twice by accident, causing my 60-tab session backup to be overwritten.

Using a third-party session manager (I have tried all the well-known ones) can mitigate this problem, but doesn't really solve it because the re-opened sessions aren't quite in the same format as Firefox sessions and so lose information. In particular, I often lose each tab's icon as well as metadata for Tree Style Tab.

Could Mozilla please consider a more robust session backup system for Firefox? All it would take (I think) is to allow the user to choose the total number of backup sessions and the frequency at which a new session is added. Thank you!

According to this article I should be able to activate autofill credit card details in my country https://support.mozilla.org/en-US/kb/credit-card-autofill But the option is no where to be found and in about:config I can see it is restricted to a few countries mine not being one. I can not change the list with countries either, actually I can not change anything nor search in about:config. I am running Firefox 140.0.4 (64-bit) EDIT I made a a master password, which then made it possible for me to edit in about:config. I added my country to the extension and now I can activate it.

I am writing an email with two photo attachments. Preview will not work (open) for me to double check the correct file is being sent. It will, however, open a file with only text.

For no apparent reason, all Firefox 140.0.4 on Windows 10 crashed and when it was relaunched it did not restore any open tabs, reverting instead to the home page. All history is gone, no previously open tabs are windows appear in the history list. This computer has syncing enabled.

I used about: profiles on the Win 10 machine and it only shows the one that is currently in use. I copied the 2 files found in the along with places.sqlite into a temp directory. I did a search for index.dat and it is not found on the Win 10 computer.

Even worse: another computer running Win 11 that is syncing with the Win 10 machine is also now missing its history. Is there a way to recover from this?

Note: I am generating this from the Win 11 machine, not the problematic Win 10 machine.

Several web sites say that they detect this ad block on my pc , but I can not find it through my pc sites. It seems to be kind of a worm that can not be disabled. I am using Firefox.

Hello,

I just closed FF (latest version) and opened it again and all my tabs are gone. I had a private FF window open, so I am guessing this is the cause.

Is there a way to get get them back?

Thanks

This happens often. I start Firefox, and on the home page is a list of articles linked to several different publications. So I'm generally already on a mission, but I think "I'll come back to that article later", and I go off to do what I logged in to do. And when I get back to the article a few minutes or hours later, it's gone! There is a new set of articles. The articles have all refreshed, and the one I wanted to read is gone. So can I see back to what that was? Or some other way to retrieve that article I never got to read before it went away?

About two weeks ago, Firefox started randomly hanging and would stop responding. It wouldn't let me close the program and I always have to restart my system to resolve the problem. Sometimes it only takes a few minutes after restart before it hangs, other times it will be fine for hours.

I've tried multiple solutions I've found online, carefully following instructions: clearing cookies and cache, disabling all extensions, refreshing firefox, creating a new profile, deleting specific files within the Profiles folder, etc.

I've yet to make it more than four hours without the program hanging.

Any assistance or suggestions are greatly appreciated.

I lost everything in a tragic housefire recently and I cannot remember the exact username I used for my Mozilla Account. Of course, this means I have also lost years of valuable Favorites and Passwords and Logins.

Is there anyway to find out what my login name was?

How can I open an ad on a one-time basis, as if there were an option when right-clicking?

Sometimes we search for something we want to buy. The ad is near the top of the search results and seems to be worth investigating.

But we can't open the ad. Our wonderful ad blocker is, like our guard dog, too zealous sometimes protecting us.

The answer I'm looking for is NOT to go into Settings, etc. That's swatting a fly with a sledge hammer.

I've tried 7 times to import my bookmarks from Chrome into Firefox. Firefox says that the import was successful each time, but the bookmarks aren't showing up in the Bookmark Tool Bar. It's only showing the older import, not the latest. If I go to one of the new pages, it shows that it is bookmarked, but the list that it belongs to is nowhere to be found....

So how do I update to the newly imported "Imported From Firefox" folder?
