It is really sad that there is no way to contact mozilla directly The update installed on my Windows 7 64 bit is now storing cookies for Proton Mail and that makes the storage amt increase from 29Kb to 78Kb and I am not happy that I can not find a way to remove or revert the update so detail steps to complete that process would be nice. As for my future use of Firefox and involvement with Mozilla I am very seriously considering NO further use of both and your claims are starting to become lies you are permitting tracking in my view of this behavior Community Members should not be dealing with these concerns GET OFF your lazy back side Mozilla

Hi! I´m using Jdownloader2. After an update of Firefox the captcha-extension of JDownloader didn´t work anymore. I reinstalled Firefox, but adding the extension is still prevented. Following quote appears: "Firefox hat die Website daran gehindert, Sie zu fragen, ob Software installiert werden soll" It should be in yellow (but it isn´t), like following site describes: https://support.mozilla.org/de/kb/Add-ons-koennen-nicht-installiert-werden#w_firefox-hat-die-website-daran-gehindert-sie-zu-fragen-ob-software-installiert-werden-soll Furthermore there should be a button to authorize the installation. Instead there is only the button "OK". I followed the help-site mentioned above to the letter, to no avail. By the way, I´m using Nightly now, but JDownloader2 automatically wants access to Firefox. Would you please tell me, how to add the mentioned extension. Without it I couldn´t download most files! Please answer to following email: [redacted email from community support forum]

I tried to open Firefox and a message appeared: "Couldn't load XPCOM". I uninstalled the program with Revo Uninstaller Pro and downloaded the latest version. I selected Run as Administrator but there is a message that says "Windows cannot have access to the selected device, path or file. Maybe you don't have access rights". However, I do have access rights. I have checked it multiple times. How can I install Firefox and see it work properly? Thanks

Κατέβασα το Firefox Installer.exe και προσπαθώ να κάνω εγκατάσταση με το Run as Administrator διότι για κάποιον λόγο δεν με αφήνει διαφορετικά, αν και έχω δικαιώματα διαχειριστή. Μου βγάζει όμως ένα παράθυρο το 7-Zip και μου λέει "Δεν επιτρέπεται η πρόσβαση".

Greetings to y’all I am setting up a Microsoft Surface pro 7. Several days ago I installed windows 11 Pro on the machine.

I have tried to review previously loaded Extensions. For each of the Extensions There is a message:

"Can’t read and change data on this site"- listed after each extension. What is this about? How do I access settings for extensions?

How much longer will the 15 minute updates that started well over an hour go on? I need my extensions back

How much longer will Firefox be down due to server updates on Mozilla.org? ALL of my extensions are disabled for that NLT 15 minute update that's been going on for well over an hour (I know, because my extensions are still disabled and have not yet reset themselves---Mozilla crapping them out, Mozilla returns them to my setup---to the way I had them configured. Specifically, the ones I'm missing the most right now are Tab Sidebar, Tiled Tab Groups, and whichever one(s) make bookmarks/new tabs open in a NEW tab, not clobbering a tab that is currently in use. I did that to open Duck Duck Go a minute ago, and had to re-write this whole support question because, for some reason, Duck Duck Go opened up in this ACTIVELY IN USE tab instead of a new tab. And not only that, it wiped the contents of this support chat window. Sorry, but that is totally UNSAT.

Thanks, jim74, [edited] @jdgblogs.com (which needs to change to [edited] @jstrack,net---how do I do that?), Firefox ESR 91.5.1esr on Slackware v. 15.

Hello, Any help would be tremendously appreciated! Can someone please tell me very briefly the steps to switch from the FF 128.8 ESR version to the latest supported regular version, which I believe is FF 136. From my research, it appears that you can download the regular version and go to about:profiles to switch your profile back to your original one used w the ESR version. Please list the very simple steps (1,2,3 etc) to switch from ESR to regular version for a non techie.

My background, I have an older MacBook Pro mid 2015, which had 10.11 installed (El Capitan) and recently took the plunge & updated to Mac OS Monterey (12.7.6), which was the highest allowed for this older MacBook. The new OS is awesome & fixed so many websites that were no longer working.

Firefox automatically moved me to the ESR version at some point with my older Mac 10.11 OS. I believe my latest supported version was 78.15 ESR. When I recently updated my MacBook OS to Monterey 12.7.6, Firefox updated automatically to 128.8 ESR.

Now, many websites recently seem to be broken (gmail, yahoo calendar, duckduckgo, & others), so moving from ESR to the most recent regular version seems like the best solution (I believe FF 136 is highest supported by Mac OS 12.7.6). Please list the very simple switch steps or point me to an article. Thanks very very much.

Several days ago I backed up my hard drive, preparing to upgrade from W10 to W11. The upgrade was very slow and took a lot of time. Also, when I began to use W11, many of the programs, including Firefox, were slow to load and slow to run. Finally, I decided to try a reinstall of W11, hoping for an improvement. For this second try, I decide to use the option that eliminated programs that, over the years, I had downloaded onto my computer, such as Adobe Reader, Glary Utilities, and Firefox. For whatever reason, this second installation of W11 took less time and programs like Adobe and Glary worked almost as well as before. (They performed a little better on W10.) But not Firefox! Firefox wouldn’t run at all. I then deleted Firefox, using Revo Uninstaller. My next step was to download another copy of Firefox, from the Mozilla website. The result was the error message I have seen on many postings on this website:

Profile Missing Your Firefox profile cannot be loaded. It may be missing or inaccessible.

As of this writing, the path C:\Users\rsuth\AppData\Roaming\Mozilla\Firefox\Profiles\ leads to two folders, both dated 11/11/2024: 0dppjrfa.default contains one file, times.json, dated 8/11/2020 and ru82tlj5.default-release, containing 97 items, files and folders, most – but not all - of the files dated 11/11/2024.

On my desktop is a folder Firefox Bookmarks. Inside is Mozilla/Firefox/Profiles/xh22l03a.Default User It contains 79 items, files and folders, mostly dated 7/16/2023

I have used Firefox for many years. It contains links to many handy and valuable websites. I hope that someone who has read this account will be able to direct me to a solution that will allow me to recover my previous Firefox and all the all the important information it contains. And, if that happens, then I will try to do something similar with my lost Thunderbird. Thanks for reading.

The current version of Firefox is very frustrating to use. It often will not let me enter a password but will send me to the saved passwords. I do not want to put all my passwords on the computer. I have 2 U tube accounts, and the new Firefox will not let me enter the account info directly, but sends me to Google. I have had to resort to using Microsoft Edge out of sheer frustration with Firefox. Previous versions of Firefox did not have these problems

Add-Ons in Menu/Toolbar Don't Reflect Those Enabled/Disabled in Settings After Restart

Hi,

I seem to be having a really odd issue where each time I restart Firefox, recent addons I've installed will not function or appear in the Add-On drop down menu (despite being meant to appear in such), despite being enabled and still being shown as such when I check settings. They only become visible and functional when I disable and re-enable them.

I've just discovered the same thing seems to happen in reverse too. I recently disabled ClearURLs due to a bug it was causing in Google Drive, yet it appeared in my Add-On drop down menu after restarting. Checking settings showed it to still be 'disabled'.

Things I've tried:

  • Restarting both Firefox and PC.
  • Uninstalling and reinstalling the effected Add-ons
  • Deleting my extension*, compatability.ini and prefs.js files - erasing all my add-on settings yet still not helping. This is the main thing I've suggested on forums like this with similar questions, but has not helped.

It seems to only be effecting the most recent set of add-ons I installed over the last week, as if Firefox keeps trying to work with the Add-on settings I had at a previous date. I've seemingly had some cases where the extensions disable or are uninstalled entirely but I'm not sure this is related, as I think it only happened once.

I suspect it's not to do with the new extensions themselves, given it's effecting all the most recent ones, but I'll list the ones I've seen it effecting here regardless:

ClearURLS (not recently installed, but as mentioned showing similar reverse effects) Undo Close Tab YouTube NonStop Privacy Badger History AutoDelete Don't Accept Image/Webp Decentraleyes Xkit Rewritten Disconnect AI Grammar Checker & Paraphraser - LanguageTool &udm=14

As you can see I recently installed quite a few anti-tracker type extensions which probably overlap in function, mainly just to test them out, so it could be connected to them I guess... but seems unlikely.

Thanks, Matt

Dear Mozilla Firefox Team,

I hope this message finds you well. I am a long-time user of Firefox and have greatly enjoyed the browser for its speed, security, and user-friendly interface. However, I recently encountered an issue where the latest update seems to be incompatible with my system.

As a user with a low-end system, I sincerely request that future updates consider compatibility with older or less powerful hardware. Firefox has always stood out for its accessibility, and I believe that supporting a wider range of devices would further enhance the browser’s appeal to users like me.

I would be grateful if there could be an option or version of Firefox optimized for systems with limited resources. Thank you for your time, and I look forward to your response.
