Been using Firefox for long time on a Win10 machine. Motherboard failed. Saved the C drive. Question is how to move bookmarks (profile files ?) from the old C drive to the new Win11 computer? I tried moving the profiles over from the old C drive to the new computer but Firefox would not recognize them and shutdown. Restored the Win11 files and Firefox is again happy.

My bookmarks toolbar is empty. When looking through the bookmarks menu, it shows that none of my bookmarks have been removed, and they are all still listed as being present in the Bookmarks toolbar, but they are not displayed in such. To be clear, bookmarks toolbar is enabled, and I have already verified its positioning in the customize toolbar pane. There is a strip of empty space where they used to be, but they are simply missing now. How do I fix whatever issue caused the toolbar to cease displaying my bookmarks?

I broke an old computer and have my logins from it on a backup drive in logins.json and key4.db. I can't work out how to transfer these logins to my new computer. I've tried creating a new firefox profile since I am nervous of losing logins that are on my new computer, but then I am totally lost.

I have an extension (completely blank) that can't be deinstalled. I am trying to use the "refresh firefox feature" to get rid of it, but the button simply isn't where it should be. The text is german, but none if these Buttons are the one I seek.

I went to settings and set firefox to open links in a NEW TAB instead of a new window, but it still opens links in a new window. I did a search on google and when I click on the link for the website to see the information it is still opening in a new window. How can I fix this so I don't have a lot of new windows. It's irritating to have to close all those stinking windows just to get back to my original window. I just want the links I click on to open in a new tab.

Firefox allow to disable access to canvas for lowering fingerprinting, it's cool !

But as web developer : i like to ask this access before try to using it,

Something like :

1. Do you alllow canvas ? 2. Show the browser part 3. Wait for user answer 4. It's OK : download PDF done with canvass 5. It's not OK : shown an error to user.

To avoid such situation (see screencast)

hey folks,

since today firefox wont load any websites out of troubleshoot mode. not even settings/ about:config. if i open a page in a new tab it just stays blank and nothing is happening.

in troubleshoot mode i turned off hardware acceleration - nothing changed after restart. i updated the runtime file "Visual Studio 2015, 2017, 2019, and 2022", which is suggested in different help-posts, i deactivated all addons, i created a new profile and also tried an imported one from eralier today - so far nothing has worked.

i also reinstalled firefox with version 99/ version 101 two times, after i cleared %APPDATA%-data.

im also just using windows defender as antivir.

please elp, i'm out of ideas.

The font size in the toolbar is too small. I mean the text on the tops describing my open tabs, the bookmarks toolbar, etc.

I cannot find an actionable answer to how to increase or change the font size. I need a solution, but not written in a tech language. Is there one?

My workflow in Firefox involves 100's of open tabs pertaining to work, personal etc. I regularly bookmark all the abs using the 'bookmark all tabs' feature in the Bookmarks drowdown (or the equivalent 'select all tabs' -> 'bookmark all tabs' by rightclicking on a tab) which offers the option of saving the tabs in a new folder name I specify. As of the last couple of weeks, the option to enter a folder name no longer exists. I've attached a screenshot of the current pop-up when I choose 'bookmark all tabs'.

Perhaps related: this may have started occuring after I upgraded to the latest version (v. 101.0 on MacOs 12.4 on Macbook Pro) or the timing may be a coincidence.

Saving the 100s of bookmarks every week is an essential part of workflow; I've been doiong it for years, and I really need to have this ability back. Please help me debug this.

Thanks!

This question has to do with logging into web sites with an email and a password. Firefox 101.0.1 (64-bit). Windows 10.

On many sites, when I click in the email field, a drop down list of email addresses appears from which I can make a selection using the mouse or up/down arrow keys. Some web sites have as few as two email addresses in the drop down list, others have many more. I recall that one site has about fifteen email addresses in the drop down list.

How can I remove a non-applicable email address from the drop down list?

How can I clear the drop down list of all email addresses?

Thanks.

Firefox says I need a video codec to play a video (that is aparently somewhere on the page). It does NOT tell me what video, what video format, or what codec I need. How do I find out what codec I need?

Firefox version: 101.0 (64 bit) OS: Fedora 36

Hi,

I use Mendeley Web Extension to pull articles and other things from Firefox directly into my Mendeley library. I will usually rapidly read through the PDF file online before deciding to add it or not. For some unknown reason, Firefox blocks the use of Mendeley on PDF file, for security reasons, and I can no longer add them to my library. Most references are only available as PDF files making the add-on completely useless. Is there a security feature that I can disable to be able to use the extension again?

Kind regards,

Mathias

so firefox I am logged out, you can tell where it say "save and sync - sign in". but even though I am not signed in, my passwords and addons are still showing up.

how to fix this

thank you!!

I've been using Firefox almost exclusively for years now, and it's always worked flawlessly - until recently! Now, when I log into my GitHub account, I can no longer edit and commit my changes.

When I click on the "pencil" on a rendered page, I am taken to the "edit page" where I can make my changes (in markdown), preview those changes (rendered in markdown), and then commit those changes. Beginning very recently (within the past few days), the preview tab is no longer functional, and I can no longer commit my changes to the file.

I've verified that GitHub has not changed their interface by logging in from my Chrome browser, and following the exact same procedure used in Firefox everything works as it always has.

I recently upgraded from ver 99 to 100, and now to 101.0.1. I recall clicking a pop-up immediately after the 99-100 upgrade that had something to do with cookies... sorry, I know that's lame, but it's all I can recall now. In any case, I am certain this happened recently.

Please help... I have to use Chrome for a couple of things already (my brokerage account at Vanguard for example), but I despise Google, and want to limit their spying.

Thanks,

Hi, I have this problem that is driving me crazy, I know it is not an issue with firefox but I really appreciate any help.

The problem is that there is a grey html code in inspector when rendering the html page, the grey code is not exist in my original file but that grey code I had already deleted it after using it a while, but it is still appears as grey code in inspector and this made me some issues in jquery.

So how can i get rid of it ?

Thanks

Hello, I've used AddBlock successfully for years but now , to my utter dismay, It has stopped functioning. I tried unsuccessfully to reset Firefox . Have just gone through the latest StartPage privacy protocol added to Firefox, but I am still beset with beastly adds. Hope you can help, Cordially, Joy
