i want to disable my spamblocker/ junk mail detector in firefox ..... it keeps sending legit emails to the spam file no matter how i adjust the junkmail settings....is there a way to just turn the spam/junk detector off altogether?

i already have spam detector through my cPanel at my webhost and another junkmail detector in antivirus/malware program on my desktop

i don't need firefox diverting legit emails that get through the earlier detectors.

I'm setting up a user on a new computer. I've exported her bookmarks from her old computer. On the new computer I go to Bookmarks > Manage Bookmarks > (select bookmarks toolbar) > Import and Backup > Import bookmarks from HTML. I browse to my folder containing the bookmarks.html file, Open it, and nothing.

I've tried all the suggestions I can find. Places Database Verify Integrity gives me: > Task: checkIntegrity + The places.sqlite database is sane + The favicons.sqlite database is sane > Task: checkCoherence + The database is coherent etc. Opening the bookmarks.html file shows a list of bookmarks. That file is not empty.

This shouldn't be this hard. How do I accomplish this?

I have to buy a new iMac, which now comes with Sonoma. Is there a version of Firefox that works without major issues on an iMac with Sonoma or is it better to wait? Thanks.

Can I transfer my existing Firefox profile on the Windows 7 machine to a new installation on a new Win10Pro machine by copying the profile from the "AppData" location onto a pen drive, and then copying that into the comparable folder in the new machine.

I assume if I can I will then need to make the copied profile the default one using profile manager?

I have used Firefox with sync since sync were released. Today (25th dec), all of a sudden hundreds of saved passwords are gone, just 9 out of at least 200.

I have changed the password for my account and logged in. Tried to logout and login again but just 9 passwords is found, extremely frustrating!

Anyone got a clue what has happened?

I'm trying to run Firefox ESR on on a Mac with OS 10.11.6. This page (https://support.mozilla.org/en-US/kb/firefox-mac-osx-users-esr) seems to indicate that Firefox ESR should work on a Mac with 10.11.6, but my computer says that Firefox ESR is not able to run on my Mac with 10.11.6. Any suggestions for how I can get Firefox to run on this older computer?

Hi, I have the problem that Firefox restarts after a crash, re-opening exactly the same windows that were open at the time of the crash, which most of the time reproduces the crash.

I want Firefox to restart with an empty window, like it is configured.

I have read a support entry that hints setting browser.sessionstore.resume_from_crash to false, which does NOT to the job (anymore).

Hello

I hope you can help.

Trying to sync my logins/passwords from my laptop to my desktop. It just doesnt work.

I have reset primary password, logged into both devices, selected sync on both devices. But it does not sync to desktop. Both machines come up in the Connected Services setion of my mozilla account.

When i try to manually enter logins & password on desktop list - it keeps asking me to enter my primary password (despite already being logged into firefox).

This is very frustrating so any help is greatly appreciated.

Hi

I had to change my operating system. before doing that I made sure I have sync my browser. Now after installation browser and login to my account the sync is not doing what I was hoping for. The sync is just uploading the new configuration to the cloud but it is not downloading all the history and add-ons from a version before OS change. I see it is stored but I don't see any option to load those to the current browser. Please, advise what can I do?

I'm using the current Firefox-ESR for Linux x86_64. Under Settings > Privacy and Security > Cookies and Site Data > Manage Exceptions, I blocked http:174.138.51.92 and https:174.138.51.92 several weeks ago. But Manage Data shows 10 cookies last used 45 minutes ago, and Remove Selection for these cookies fails (incidentally retaining the "last used" value), even when repeated multiple times as fast as I can mouse the select, then Remove Selection, then Save Changes then Manage Data .

How can I delete these cookies and site data? And why does it fail for this site and this site only? And how can I block them permanently, short of black-holing that site in /etc/hosts?

When I click on a Firefox menu (File, Edit, View, etc.) or the hamburger menu, or a drop-down menu on a web page, the menu appears. Then, when I move the mouse to hover over the menu, the menu vanishes. If, instead, I hold down the mouse button, I can move over the menu without it disappearing.

I'm using a focus-follows-mouse window manager (VTWM) and I think, somehow, Firefox is getting a focus change message when the mouse moves onto the menu. I think this because of the way the Firefox titlebar flickers from showing it's the active window to the inactive window, then active again, once the menu disappears.

Please advise.

Thanks, Richard

Im trying to halt fingerprint tracking, whoever designed Firefox's privacy.resistFingerprinting rule makes fingerprinting even more prevalent.

With privacy.resistFingerprinting set to FALSE, my resolution is reported : 1920x1080x24, set to TRUE its 1920x968x24

1 in 6 browsers has resolution 1920x1080x24 1 in 6000 browsers has resolution 1920x968x24

Who in Firefox decided this config rule? and what is the logic behind it? Looks like intentional sabotage to make peoples browsers more trackable.

Whilst leaving resistFingerprinting set to TRUE, How can I force my resolution to the more generic 1920x1080x24?

Is there another setting in about:config I can change? if there isnt, where can I request this feature? Id rather not resort to an extention for something so small like this.

I am trying to print specs for a computer (beck & front) at:

https://www.dell.com/support/manuals/en-us/xps-8960-desktop/xps-8960-setup-and-specifications/back?guid=guid-f2dda353-ba5a-44c0-b85f-6bf1b8c70d15&lang=en-us

The print-out with Firefox captures only half on the picture and relevant info. Luckily, Safari prints correctly. I am wondering why can't Firefox do the job so I do not have to go to Safari for printing? This issue is not specific to this website, it happens often in many other cases. Is this being worked on? Thanks.

When a new bookmark is created it goes to the end of the bookmark listing in the left panel. How can I force Firefox to automatically put each newly created bookmark in the correct alphabetic position in the left panel Bookmarks panel? I DO NOT want to alphabetize the entire panel, I just want each newly created bookmark to go where is alphabetically belongs. I do not use folders so have one long list for bookmarks menu. thank Bob

Hello,

Is there a way to export tabs to a PDF file? I need to rebuild my PC and am backing up everything. I have a ton of tabs open. Can I export them somehow so I can import them after I have reinstalled Firefox?

I've searched but what I find doesn't match what I see in my browser as far as menus, etc.

Thanks for your help
