What version of Firefox actually allows you to add extensions? I'm running the most current version of Tumbleweed that ships with 144.0. Attempts to add extensions just sit there doing nothing until I close the tab. This sort of worked some time ago (I forget the version) but the inability of Firefox to allow add-ons/extensions is getting to be a joke. There are other browsers out there, ya know.

If I go to the profile folder, exit firefox then copy and paste the folder to a backup location. The attempted backup fails. Something about permissions as I recall. I have tried many things unsuccessfully. Something has changed that does not allow for the backup of profile folders. Adding a backup option to the profile manager would be nice. I noticed some people have found work-arounds but I need a straight-forward procedure for backing up my folders. No work-arounds please, just a simple procedure. May I ask for help with this issue?

Firefox used to have my background colors, and on the latest update, my pull-down menu and tabs are robin's-egg blue. I can't figure out how to get my colors back, and I hate that color.

How the hell do I get back control over my colors?

Certain PDFs only allow page view when opened in Firefox. When opened with other PDF viewing software or browsers (Microsoft Edge, Adobe Acrobat, Google Chrome), these PDFs allow continuous scrolling. I don't have this issue for most PDFs.

I've tried fixing the problem by editing the PDF settings in Adobe Acrobat but to no avail. When combining a PDF that works fine with a PDF that doesn't allow continuous scrolling in Firefox, it seems to take on the settings of not allowing continuous scrolling.

Examples (these link to documents from a Florida public document database): Example 1 (made with Power PDF Create) Example 2 (made with Adobe PDF Library): https://depedms.dep.state.fl.us:443/Oculus/servlet/shell?command=getEntity&[guid=5.506115.1]&[profile=Cleanup_Remediation]

Dear Community,

Since more than a month, when firefox was updated, all my bookmarks seem to be gone,which includes a lot of valuable research made over the past few years.

I have tried all suggestions that google give me to restore my bookmarks, but as far as I understand, there are no newer ones since 2019 (nor older ones than 2018) on my computer? That's what I find in a folder called 'bookmarkbackups' with json-files. Separately I also searched for 'json' and '.jsonlz4' and found nothing after 2019. Also I searched for .html, but nothing seemed to contain bookmark directly.

When I go to manage bookmarks > 'import/export' icon in the upper bar, it suggests two options, for 'nov 13 2025', or today's date), of which none provide me with any bookmarks.

Can I somehow still recover my research?

Do I really need to backup manually?

Or need I start saving all URLs in a word-document for my new research project?...

Firefox seems to update regularly, I currently have version 145.01. (I work on a Mac 2021, with Ventura 13.7.8)

I highly appreciate any advice on this matter.

Kind regards, Maria

I tried several things, but nothing helped so far. I did an offline-scan with Windows Defender, I opened FF in troubleshoot mode, cleared cache etc. I got the following crash-ID:

bp-7a77a8ad-7637-4fba-bd20-9e4730251209

Maybe someone here is able to help me. Thanks in advance.

Tell me how to delete all my comments that I have made at Mozilla. None of my comments are valid and I wish to have them all deleted.

If you can please delete them for me.

I hover over bookmark folder, they expand, and the links the folder contains work. (Or) now 80 percent of the time, I hover over the bookmark folder, they don't expand, so I click on the folder to expand it, and 90 percent of the time, the links in the folder do nothing when clicked on. They won't even get highlighted, (selected) I restart firefox, and all works again, for about 10 seconds, and problem occurs again. It goes without saying it gets real frustrating restarting firefox over and over and over again to use another bookmark. I've never experienced this before. This only happens for me on firefox for Linux Mint 22.1. Firefox on windows 11 does not exhibit this problem. Please help, thanks. Cheers...

Hi! Was just wondering if there was something preventing me from opening these kinds of pop-ups. Recently, I've been browsing old websites and noticed that links that are supposed to be pop-ups don't pop-up at all. Then, I tried to do the same on my website, and it still didn't work. I've pretty much done every solution I could find under the Sun, but none so far have worked whatsoever. Is this a new feature or is Firefox just being weird again?

Please help ;_; it's been stressing me out real bad for the past few hours!

The subject says it all. The "tabs from other devices" are a) Shown as a long flat list of links, not in their individual tabs, which is disappointing b) right click does nothing - doesn't open them as advertised

So I reformatted my hard drive and everytime I finish I reinstall Firefox. I have an account where I log in and it put me back where I left off with all my past bookmarks that I saved. Ive been doing this for 10 years but today not sure whats going on but when I logged if all my stuff has disappeared. Please help or contact Mozilla regarding this. I cant understand why one cant directly speak to the ones who developed this browser. Quite frustrating

As of 12/9/25, Firefox seems to now prevent Theme add-ons from working if there is a contrast setting configured in Windows configuration. (Version 146.0) Previously, this allowed a very aesthetically pleasing view. I would greatly enjoy having that option again. Thank you.

Hello I got a pop up or it was new tab informing about new firefox functions. It was about profile creation and management. Now i have two profiles and cant switch back to my old one. I cant seem to be able to delete new profile to return to my old one.

When I export a presentation from Perplexity in Firefox, the downloaded file is completely empty (slides without content).

If I do the same export in other browsers (for example, Chrome or Edge), the presentation exports correctly and the file is not empty.

So it seems this issue only happens in Firefox. Firefox 145.0.2

Hello, I just updated to Firefox version 146, and now the bookmarks and history in the sidebar are no longer visible because the background is yellow-green and the text is white...so, invisible!

I hope you will fix this quickly with a new update, as it's a real problem.

Thank you in advance. Sincerely,

When I turn on my Mac and click the Firefox browser icon, it will not load. It hangs. I get a "not responding" message and have to "force quit," again and again until FINALLY it loads, after five or more failed attempts. This does not happen with Firefox on my laptop, only my Mac. Both Firefox and my Mac are up to date. Why is this happening? Please help. It happens every day when I try to load the browser. I am about to give up and move to Safari. Relatedly, anyone know if it's possible to export all my bookmarks from Firefox to Safari?

TODAY'S (NEW-ish) ISSUE: - Multiple times per day I Click the Yellow button Top Left Bar to shrink and put App in dock to open again later. When I re-Large FireFox shows EMPTY FireFox Bar like I "Quit". Each time need to go to History and RE-OPEN ALL TABS??????

1. 2 within THIS text box just now, I highlighted the words: "Today's Issue" and clicked BOLD - instead it added a 2nd set of parenthesis???? WTF?

Browser is open all day. Always multiple tabs open/signed in, Paid & non-paid Apps, Email boxes, Wix, etc, many website tabs up, I do a lot of "research" - to pay my $rent and/or live my life using this "tool". Is my typical behavior. IN THE MIDDLE OF DOING WORK - I need to fix re-load Firefox again and again. . . Interrupted, distracted, observe, deal with so many Tech failures every day from ALL brands, I am struggling to keep my "life" functioning.

470+ issues/articles counted in the 11 subject boxes - in HELP section. FOUR HUNDRED-SEVENTY.

Thank you to "Volunteers" responding to help / issues!! Do you do any MENTAL help volunteering? kc
