I have a problem with opening files: Mozilla keeps saving them and ignores temp folder. I tried to modify browser.download.improvements_to_download_panel in about:config, but nothing happened. Can anybody help me?

Hi there,

i'd like to copy my Firefox profile from PC1 to a new PC2;

Last time i tried this, i ended up with PC2 having the same "name" as PC1 in "Sync". This caused weird sync issues, as the system thought my PC2 was PC1 as vice versa.

So, is it possible to copy my entire profile with all addons/settings, BUT, make "Sync" recognize it as a NEW pc ?

Thank you in advance :-)

After this latest Firefox install, my zoom percentages are wonky. They were set at 100% before but now I have to adjust them to around 70% for the same zoom effect, but that doesn't fix how much taller the tab space is and bookmark space relative to the previous version.

When I installed version 103 on Windows 10 yesterday, the Tabs, address panel row of icons and the onscreen bookmarks icons doubled in size pushing about half of them off screen. Can I get them back to the size the were?

I keep them on screen to facilitate use and work more effectively. Pushing them off screen reduces the effectiveness of Firefox for me. I spent too much time today trying to find options that would allow me to revert to the former format without uninstalling v.103 - without success.

HELP!!!!

This is a very bizarre problem. Basically I can't install any Firefox addon neither on my desktop OR may laptop. I noticed this issue just couple of days ago. When I try to install any addon normally, from a link, it tells me that the addon can't be installed because the file is corrupt. Tried several addons, all same problem. On my desktop AND on my laptop. On my desktop I'm running ver. 103, but on my laptop I still had ver. 102.1, so there is no Firefox update issue. When I try to install addon from xpi file, it tells me that I have no permission to open that file and that's it. I tried to take ownership of that file but it didn't solve the issue I tried to disable my AV program, but it didn't do anything. On my laptop, I tried to refresh FF, no help. I tried to start FF in safe mode, same problem. I created new profile, same issue. Eventually, I totally uninstalled FF, removing program itself, removing Appdata folder and even registry entry. Installed fresh copy of FF, same problem exists. Then, I noticed one thing. When I tried to sync fresh FF installation on my laptop, it synced everything, EXCEPT for addons. So, something is preventing me doing anything regarding addons. Themes install just fine. I've struggling with this problem since yesterday and at this point I totally ran out of any fresh ideas how to solve this issue, thus posting here. I'll appreciate any fresh idea as what to do next. Thanks

Hello and thanks. I have a new PC hard drive and need to reinstall browser. I logged into my Firefox account online but cannot find the answer. Is there a way I can install my browser with my old bookmarks and/or history? I am running Windows 10.

Referring to this forum post, step 2 of the chosen solution no longer exists. Please help.

‘Firefox updated and everything is very large by half again, went full screen was not setup for this,web pages show up very large only read 25 to 33% of a page can not control FF anymore’ I am disabled vision and physical ; now almost impossible to use FireFox

I'm currently using a Windows 10 desktop computer most of the time, but will need to use a Windows 11 laptop for research travel several times over the next several months.

Will it be possible to copy my profile from Win 10 to the Win 11 computer, use the Win 11 computer for a few weeks, and then copy the profile back to the Win 10 computer?

Or is there something different about Firefox working with Win 10 or Win 11 that would keep this from working for me?

(BTW: Using Sync would probably not be feasible.)

Advice will be much appreciated!

I have my saved login and password details from another browser in a CSV and would like to import them to Firefox. I initially did not have the 'Import from a File' option in the drop down menu of the Logins and Passwords tab. After following a guide that instructed to set signon.management.page.fileImport.enabled to true in the about:config page, the option appeared. However, the said option is unresponsive to any clicks. The drop down menu simply closes once the option is selected, without any other reaction.

I'm not sure if this is a related problem but I am also unable to use the Import Wizard that appears on performing Alt+F and choosing 'Import From Another Browser...' The Import Wizard window only appears with a message that says "No programs that contain bookmarks, history or password data could be found."

Funnily enough, the 'Browse..' button for adding images under this support question doesn't work either.

I noticed a glitch with the way my mouse was working in FF, but on Nightly 105 it was fine, so I installed the candidate for 105.1b into my FDE installation folder. Now will this candidate update to the next version of beta automatically, or will I have to install 105.2b myself?

Hey all , i made backup via "export passwords" via password tab and i came back to my pc to and tried to import via csv file but when i pick my csv file nothing happens , any ideas ?

Hello - I've been looking around the Firefox site, and the Internet in general, and so far haven't found out the answer to my question: how do I get Firefox 104 to work on my Linux Mint 18.2 Cinnamon Sonya 32 bit? Specifically what I haven't been able to determine is whether or not I first need to upgrade my Linux, which I suspect. And if so, what's the minimum level of the OS that is required? I may be overlooking the simple answers, but so far I cannot find them. And so far the Firefox website upgrade feature does nothing that I can detect. Thank you for any assistance - Doug.

"OpenH264 Video Codec provided by Cisco Systems, Inc." plugin will sit in the "will be installed shortly" status forever if you have HTTPS-Only mode enabled. I have been pulling my hair out for the last few days trying to figure out why I couldn't play YouTube or many other sites videos.

Turns out the site that the library is downloaded from has a bad certificate installed: https://ciscobinary.openh264.org/libopenh264-2.3.0-linux64.6.so.bz2

``` Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for ciscobinary.openh264.org. The certificate is only valid for the following names: a248.e.akamai.net, *.akamaihd-staging.net, *.akamaihd.net, *.akamaized-staging.net, *.akamaized.net

My wife has an older Mac. About a week ago, a pop-up from Firefox told her to update her program. She loaded in the new one and when she tried to open it she got the message that her computer was too old for the update.

We had to reload the most recent update which had been running on her computer.

Now, none of her bookmarks show up and the bookmark toolbar will not display near the top of the screen as it used to.

None of help items online are of any use because what they say will show up on the screen (such as when you enter "about:profiles") is not what shows up on her screen.

Is there any way to recover her bookmarks, passwords and other saved data, please?
