Diễn đàn hỗ trợ Firefox

Hi there, I'm hoping someone can help with this. I recently signed into a shared computer with my personal Firefox account, and it automatically imported all my history, my browser extensions, and bookmarks, including personal/secure information that I wouldn't want on a shared computer. I tried signing out and deleting the sites and login information, even going so far as to completely delete all of my browsing history and cookies and signing in with another account, but all the supposedly deleted history and logins and extensions were then transferred to this second account. I have deleted all my data, even uninstalled and reinstalled Firefox, and all the data from my personal account keeps haunting me as suggestions when I type in the task bar or suggested usernames when I log in to websites. How can I actually delete this information so it's not on a shared computer? Thank you!

Using firefox in linux mint 19.3 mate. Until firefox 97, I could control the size and color of the firefox scrollbars with a system CSS. Since a firefox update to version 98, firefox ignores those settings. Nothing has changed in my firefox settings, my about:config, or system settings. But now the scrollbars are barely visible low contrast narrow bars that are unpleasant to work with, and I can't figure out how to change this. suggestions? tnx

I seem to have gotten something called Google Ad Services. It frequently interferes with my getting to websites and I cannot find how to block it or remove it. HELP!

I recently made the switch to Firefox. I attempted to use the version downloaded from the internet, which I already had installed for a long time, but it would not open. I then used the version available on the Microsoft Store, which worked fine. Eventually, Firefox crashed and would not reopen. A message saying something along the lines of "Are you sure you want to start Firefox in safe mode?" would appear for a split second, and then close. I tried:

-Starting Firefox in safe mode, but nothing happened. -Restarting my computer. -Reinstalling Firefox. -Running as administrator. -Checking it is not blocked by antivirus. -Using the profile manager to create a new profile: The .zip file version opens but does not help, and the version opened by using the "firefox.exe -P" command in Run suffers from the same problem as the browser and opens for only a split second. -Attempting to boot my computer in safe mode with networking, however, the Microsoft Store listed Firefox as uninstalled, and the network menu would not display any networks so I could not reinstall it. -Searching for any Comodo iseguard.dll files, but I found none.

The only thing that worked was searching "Mozilla" in files and deleting everything except what my computer said was part of the system. After that, I was able to open Firefox, but after a short amount of time, the problem started all over. I have no clue what to do and looking all over for solutions is driving me nuts! Please help!

My address line is red, and their is an icon which say: browser is under remote control, reason: DevTools.

I am not sure how to fix this, or what to do about this. I do not know if I caused this myself. Please let me know if anybody can help.

The root problem is that when I try to open a movie in a web browser, I get the message "Oops. Your web browser is no longer supported. " see attached.

1370719 had a response that made no sense to me.

Is there anyway to fix this issue?

I have to curate and compile sheets of announcements for a local humanitarian service provider forum. I do this by sifting through my Office 365 emails, and double clicking those that contain announcements so they open a window, then sorting the windows on a second screen, then read them, summarize them, file the pertinent information with links for my summaries, and when I get a page of them, send them out. I usually start with about 15 announcements on my other screen, and it takes me some time to get them all sorted and cascaded in order for the curation.

Some of them link to PDFs which Office 365 doesn't always preview and I click download, and this used to open them in the main browser window in a new tab, where I could read them and then save them. Recently, this behavior changed and they now open right in the window the email is in, with no bars of any kind or tabs to get out of them again. I hit the stack of pancakes button, and it had a tab marked Exit, so I thought that would exit me from the view.

Instead, counterintuitively, it exited me completely from FireFox, closing all of my carefully cascaded windows of announcements, and my main browser window with Office 365 in it and everything else.

Thanks a bunch. 1) What was so wrong with the previous setup that you needed to change it? 2) How for the love of whatever the author of this new "feature" was smoking, do I get it to revert to the email or is opening these attachments by "download" no longer possible without punting the whole thing to exit? 3) Does this mean I need to permanently disallow Firefox as the browser for all my PDFs or is there some way of doing something non-fatal to my work on a per-boot basis?

On Microsoft Edge, whenever i type the first letter of a word it will suggest automatically the recent words that i have use. How to enable it on Firefox, i already browse the settings? I really need it on my job specially doing reports. We can only use Firefox to access our websites.

This is the third time I've lost all my passwords (and logins) since the beginning of the year. I had over 200 when I lost it the first time. I've entered over 75 since then and today I just lost those. Fortunately, I had a backup of my profile. The old "key4.db" and "logins.json" files I had didn't work, although they have a significant size. In fact, looking at the "logins.json" using VS Code I see the logins are there but they don't display in the "Settings > Privacy & Security". How can I get access to them when this happens again. I was able to restore the profile from several days ago so I'm not completely in trouble.  :-)

Firefox is steadily being unusable for me. On numerous occasions websites fail to show log in pop ups etc which work without issue in Chrome. Latest example : https://www.gog.com/en/games Clicking "Sign in" should show a pop up to allow me to sign in. In Firefox this does not show. I thought it may be a "pop-up" issue, so deselected "Block pop-up windows" in settings. Still the same. I added the website as an exception and still the same. Anyone have any ideas what is going on ? TIA, ZTB

Hi, I wonder if someone can help me log into the KeyBank website. I keep getting this message: "Due to technical concerns, your current version of Firefox is no longer an option for KeyBank online banking. Nothing is wrong with your account. You simply need an updated browser – like the most up-to-date version of Microsoft Edge, Google Chrome, or Mozilla Firefox – to sign on to online banking." My Mac indicates I have an up-to-date version of Firefox (78.10.0esr (64-bit) Thank you

When I try to download a file, the download always fails. This happens no matter what website I'm downloading the file from (see screenshot 1).

This started happening within the last week or so. We are running versions 97 and above.

Firefox is configured to always ask where to save files to (see screenshot 2).

Write permissions to the user's Downloads folder is denied for reasons unrelated to this issue (see screenshot 3). When I re-enable write permissions, the problem goes away.

Has anyone else run into this problem? Is write access to the Downloads folder required now, even if Firefox is not configured to save files to that location? Thanks!

The behavior of FireFox saving PDF files has changed. I am using WIN10, FireFox 98.0.1 and have it setup to use windows default application and always ask where to save for PDFs.

BEFORE the problem: The PDF opens in Acrobat Pro IX. After clicking save I would be asked, where to save. I select the location to save the PDF. Then after this, subsequent PDFs downloaded would be saved to the last saved location. This process would repeat for a new website PDF load and save. This is the behavior I want now.

NOW with the problem: The PDF opens in Acrobat Pro IX. 1. Immediately, after a reboot, the save icon on Adobe is grayed out. I select save as and point to the desired directory. 2. For any subsequent PDF opened, the Adobe save icon is available. Files are saved to the desktop.

Please note I believe I once did get a popup asking where to save and I know I selected desktop.  Since that selection I am no longer asked where to save.

Please note I have looked and tried some of the suggestions at: https://support.mozilla.org/en-US/kb/cant-download-or-save-files#w_choose-a-different-download-folder

but some of this advice needs to be updated for the new FireFox version--ex no JSON file is found at the file location covered in the advice.

I believe this issue started after the last FireFox update. Please help me restore behavior listed above under “BEFORE the problem”. Thanks.

The Motherboard on my Windows 7 gave up, however the SSD that it was on is still working properly.

I have seen it on an alternative Windows 7 computer.

I specifically wish to recover the the Bookmarks that is on the Mozilla Firefox browser, and also all of my emails on Mozilla Thunderbird.

I would be most grateful, if someone can please tell me how this can be done?

When I open Facebook with Firefox all of the images in the FB session are blank, and they will not open in the usual manner. Also only about 1/4 of the FB session is displayed.

When I use Edge I have no problems at all, so I have to assume that it is FF and not my computer that is at fault.
Please advise.
