Firefox supportforum

I get the following message when going online with Firefox: "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." I've followed all the prompts to restart the computer, refresh the computer, delete the favicons.sqlite and places.sqlite and it won't allow me to delete them. This happened yesterday as well. Yesterday I could delete those files and everything was restored. But today I can't get it to work.

I'm using the OneTab add-on, Enabled. The icon no longer shows on the Toolbar, though it is on the Menu bar next to Firefox View.

I ran Remove and then Added it again, hoping the Toolbar Icon would reappear = no go, And I lost all URLs already saved, stupid me. To be clear, clicking the Icon on the Toolbar saves all open tabs.

Is there a fix via Preferences? Thanks. gw

My Firefox browser is up to date but I cannot log on to my Bank website. As soon I enter my Logon info I get logged out, however I can access the site using MS EDGE. This is a recurring problem. The website recognizes Firefox as an valid browser. Occasionally I have been able fix problem by clearing the browser Cookies/History but at present none of that works. Do you have any suggestions? My preferred browser is Firefox so this problem is frustrating.

I don't like getting recommendations in Pocket that you need a subscription to read. Why waste my time giving me the initial information on something, but then when I try to read it, I can't because I already have too many subscriptions. Seems like there used to be an option besides "Dismiss" to not show content from particular sites?

Firefox Setup 125.0.2.exe popped a flag on Jotti's malware scan: ClamAV: Win.Trojan.Spora-7724442-0 I know this is going to turn out a false positive because VirusTotal came up with no flags but can someone at Mozilla get this flag cleared at Jotti's/ClamAV ? thanks

I have logged out of one Gmail account and want Firefox to use another, but Firefox ignores the one I want to use. How do I get Firefox to recognize a certain Gmail account so I can receive mail?

I'm on a Mac running Monterey 12.7.4. I've been using Firefox for years with no issues. All of a sudden Firefox can't load any websites. Message: "We can’t connect to the server at www.XXX.ca." But Safari loads all websites with no problems. I can't figure this out.

I recently updated to 125.0.1 and now get 'failed to check for updates': - when I manually check (help > about Firefox) (see image) - in 'settings' it also shows 'failed to check for updates' (see image) I never had such a problem with previous versions; any suggestions?

Twice in the past 2-3 weeks I have had to restart the computer, Linux Mint 21.2 Firefox 124(when updated in the past couple of days), due to the mouse freezing up and not being able to move the mouse on the screen. That's not the current problem, but it might help direct things to the final solution.

After the most recent reboot last night now I'm having a rather problem. The up/down arrow keys are no longer scroll me up and down a webpage like they always have in the past. Instead of doing smooth scrolling like they always use to, now they are scrolling me up and down the links on a web page. For example, if I were to be on youtube it would first want to scroll me down the left side links before taking me through each and every video link, when the page goes to load in more videos than it wants to go back and scroll me down the left side links again. It acts like it is taking me through the html code, line by line, instead of scrolling me smoothly down the webpage. The only way I can scroll smoothly down the webpage is to use the mouse on the scrollbar on the right side. It does this both in normal mode and in Troubleshooting Mode.

I have checked and beret scrolling is false as well as beret_shortcut. Use autoscrolling, use smooth scrolling, show scrollbars and always underline links are all clicked on. Always use the cursor keys to navigate within pages is unclicked. I have tried different changes between clicking on and unclicking those options with no change being noticed.

How can I get this back to the way it used to run?

Hello, I have problem with firefox. When I try download from facebook page files .docx, .xlsx (Microsoft Office) Firefox automatically download it as PDF and file is broken. I don't know how to repair this. Please help, it is very frustrating.

I am a Salesforce (improveit! 360) user, exclusively browsing with Firefox for over 12 years without any problems. The most recent Firefox update 125.0.2 (64-bit) has caused an issue with my staff calendar. I have reached out to improveit! 360 they are a force.com developer and they will not help, said the error is caused by Firefox interpreting the code. I have figured out a work around to get the calendar to load correctly for a short term solution. Below is a screenshot of the error, any help would be greatly appreciated.

Hi,

I have managed to figure out ways to remove items from context menus from various pages here and around the web however it always seems to leave an additional unwanted separator line that I cannot find how to get rid of.

There are a number of additional lines I am looking to remove but the current one that is annoying me (based on most usage) is the additional line between 'Copy Link Without Site Tracking' and Search which is an add-on - Simple Context Search - https://tinyurl.com/yck5c (as shown in the attachment).

I did have 'search google for...' directly above the 'Search for Google' option which I removed.

I also removed 'Copy Link' which was above the 'Copy Link Without Site Tracking' option which I also removed.

Hope the above makes sense and any help greatfully appreciated.

Thank you

Greg

I received a scam Apple (security) popup (on which I never clicked) and from that point on, some 30+ obsolete tabs congregate across the top Firefox browser window. How do i lose all these unwanted tabs?

Good morning, I have a problem with disappearing bookmarks, but I can organise the backup of the places.sqlite, but I assume that won´t be enough to recover, therefore my question is, which files would be needed or is the one mentioned sufficient?

Thank you very much,

Mike

A blank survey pops up in my homepage each time I open Firefox, I haven't filled it yet since I don't know what it entails and what it is about. There is no option to close it either, and it seems bugged as it isn't going away even after updating the version of Firefox, it is still present on 125.0.2 version. Kindly assist regarding the same. I have attached a picture of the same herewith.

I'm running a UI deployment with a web-app and Firefox on an Ubuntu system.

I'm running Firefox with the flag "--kiosk" to place it into kiosk mode (booted from the command line upon system boot). This works fine, and boots up Firefox to the page I want (my web-app) in kiosk mode (full-screen, etc.)

However, I get very annoying popups that are not acceptable for deployments in front of customers. I have tried, but CANNOT suppress all of them, or, when I thought I did, they came back a month later.

Popups:

1. "Keep pesky trackers off your tail. Open my links with Firefox" 2. "Welcome back" 3. Others like this...

These are Firefox browser popups, not related to popups that other websites can put up, and block the entire screen with an overlay until they are dismissed. My deployments are only going to a single web-page that I control (which has no popups) and there is no keyboard on the deployed system, so people cannot navigate elsewhere.

Things I've tried:

1. Firefox is installed via snap, which provides "snapshotting" configuration for the Firefox snap. I loaded Firefox, cleared the annoying dialogs, and then took a snapshot (theorying that I set Firefox configuration when doing this, and I capture that in the snapshot) and re-installed it onto a new system. Still go popups 2. Looked into user.js preferences. I can install this file onto the system, so I looked through https://searchfox.org/mozilla-release/source/remote/shared/RecommendedPreferences.sys.mjs and this is how I initially got all the popups to disable themselves. I looked through that list and tested most of the recommended settings until the popups disappeared. However, after a month or so, I'm beginning to see the popups again.

Any suggestions from Mozilla or others that run into this issue?
