I have Firefox version 136.0.2. I think it was quite recently updated. The right click menu is broken. The choice list is much longer, and the choices "open link in new tab" and "copy link" (ones I tried) do not work. This only started happening this morning. Right click works fine in Chrome. Screenshot included.

I understand that as from 14th March 2025 I will need to update Firefox. I am currently running 102.0 and have sucessfully prevented Firefox from updating to later versions. I did this to prevent the updates positioning the tabs in the wrong place. Please can you tell me if the CSS script that I use to put them back into their correct position, i.e. below the Bookmarks Toolbar, will still work.

Also, will newer versions allow the user to choose where the tabs are positioned? It was possible to do this in earlier versions and the choice is also available in other browsers.

I have also managed to stop Windows 10 updating for several years too, Microsoft kept altering my laptop in unacceptable ways.

Hi,

I am developing a website of my own and in that website I want to implement a handler for Content-Security-Policy violation reports. I want to test if this handler works as I expect and therefore I have configured a webpage such that is will report CSP violations (I see them in the web developer console) and I want to have them sent to my application's CSP-violation handler.

In my test environment, the application is running on localhost. I have run my web application both on HTTP and HTTPS (with a self-signed certificate), but in neither case Firefox is sending any reports to my application.

My CSP headers look as follows: Content-Security-Policy: report-uri http://localhost:5281/csp-violation;base-uri 'none';default-src 'self';form-action 'none';frame-ancestors 'none';report-to csp-viol;script-src 'unsafe-eval' 'nonce-9FuQ3NuVoW66DT1ZU4w9EPSymnHE1/hg';style-src 'unsafe-eval' 'nonce-9FuQ3NuVoW66DT1ZU4w9EPSymnHE1/hg' Reporting-Endpoints: csp-viol=http://localhost:5281/csp-violation Report-To: {"group":"csp-viol","max_age":10886400,"endpoints":[{"url":"http://localhost:5281/csp-violation"}]}

When I run my application using HTTPS, all HTTP in the endpoints will also be HTTPS.

I have verified that when I post something by hand to http://localhost:5281/csp-violation, my handler is executed, so that is not the issue. I believe that Firefox is just not sending the reports. Is there a way to configure Firefox such that it will send the CSP violation reports to my application when run on HTTP(S) on localhost?

Sincerely, Marcel

I have check spelling enabled in Firefox. I use Firefox in English for technical reasons, but I write most of my emails in Hungarian. I was prompted to install a dictionary addon to be able to use Hungarian spell checking. I did install that addon, however I still can not choose any other language to spell check in but English. I would like to resolve this issue. My Firefox installation is very fresh, I am leaving Chrome in favor of Firefox and would like to stay. What I would have expected is that I install Hungarian, then the spell checker automatically identifies the language pack it needs to use.

I pay my utility bills online and the utility company websites won't load in firefox but do in edge. Also various other sites wont load with an error message captcha incorrect, but no captcha shows on the screen. It's getting frustrating waiting for websites to load and getting no results. Thank you, Ann DIngee

I always use the middle mouse button (pressing the scroll wheel) to open and close new tabs, but since the update, it doesn't work anymore and now types "=" if the cursor is in a text field. For context, I use an MX Master S3, mapped with Logi Options+.

Anyone else having this issue? How do I roll back to the previous version??

SOLVED: It was a bug with Logi Options+, not Firefox. When I hovered over the tab for the presets I had for CaptureOne, I noticed it also said Firefox. So seems something weird happened there. Deleted that preset and the issue in Firefox went away.

I couldn't find a way to delete this thread, though.

I have Firefox on two Windows computers and was wondering what is the proper way to sync them.

One computer is not used often and I want to sync Firefox on it it with the Firefox on the computer I use daily so I want the Firefox that does not have the updated files updated using the Firefox data files on the computer I use daily and not the other way around. So what is the correct procedure to do this other than to make sure the Firefox program version is updated on the computer that is not used often?

Thanks

I can't find a place to control third party cookies in the Security section. I used to be able to donate on my church's website but now it doesn't work. I tried doing it with Microsoft Edge and it worked fine. I hate to erase all my history and cookies because it takes away log-in info on my regular websites. Any ideas? Thanks for your help Terri

My son's email messages are being blocked. As far as I know he is the only one. Also, when I try to open a site from the email function, it just keeps searching... This appeared about two weeks ago. I searched for "Blocked Email" and only one has been blocked; a conspicuous spam.

My Firefox browser has been crashing for a while now (Years). It's fine playing YouTube and BBC iPlayer but when I advance the time marker to a different part of the stream or video, it crashes. It also has a problem when playing slots. It seems to crash a lot making it impossible to play.

I have tried using Firefox in Troubleshooting Mode but the same things happen.

Here's the crash report ID

Many thanks in anticipation and I hope someone can help me fix these issues.

Cannot Log on to Costco.com site after update to Firefox 133.0 in Win 10 pro on 2 computers. Both are up-to-date with latest software.

Entering valid account and password cause the Costco logon page to freeze for a minute then returns to log on screen with no messages about failure

Same behavior on two computers. Log on to Costco via Microsoft Edge works perfectly (on 2 computers before any trouble shooting ). Logon with Firefox 133.0 works with every other site that I regularly use - Samsclub, Amazon, Yahoo mail, my own mail servers, NYtimes, WashingtonPost, Google, Walmart, and others

Trouble Shooting Steps taken with no change in the problem logon to Costco + Cleaned cache / cookies + Disabled virus protections + Disabled firewall + Stopped all security services + Rebooted + In settings | Privacy & Security: Added Costco.com as Exception for Enhanced Tracking protection + In settings | Privacy & Security: Added Costco.com as Exception - Cookies and Site Date

After updating to version 137 today, all my bookmarks are gone. I've tried looking under "Profiles" to see if they're on another profile following the instructions from https://support.mozilla.org/en-US/kb/recover-user-data-missing-after-firefox-update; there are two profiles (default and default-release) and both have no bookmarks. I also tried following the instructions at https://support.mozilla.org/en-US/kb/recover-lost-or-missing-bookmarks to import a backup, but Firefox finds no backups to import from and there's no "Old Firefox Data" on my desktop to restore from. Search history and recently closed tabs history are intact, so it doesn't look like Firefox has completely destroyed the profile it was using before the update, just the bookmarks. Is there anything else I should try, or should I accept that this particular library of Alexandria has burned and just begin recreating the bookmarks?
