All the theme changers do not work. Are they malfunctioning? Not updated to the current version of Firefox? The themes worked on older versions of Firefox. Can this version be corrected for Firefox? Thank you!

Hi. Sometime over the last day or so I started having a problem with my 1Password Password Manager, an extension to Firefox that imports my ID and password to websites that require them. I am running Mac OS 15.4.1 and Firefox 138.0.3. Up to now it was enough to click on the 1Password icon on the right of the first "email" box. But now I get a popup saying "Press the 1 Password icon in your browser's toolbar to unlock". But I cannot find that icon in my Firefox browser. I assume it is a Firefox problem because I do not have the same problem when using Safari and 1Password. Help appreciated, ChrisD

Lately, whenever I try to open a PDF from a website open in Firefox, the tab crashes and the PDF does not open. An error stating that the Windows file-dialog has crashed is displayed at the top of the tab. I tried to attach a screenshot of the error but that action only generates another error.

This condition does not occur when I try to open the same PDF from the same website open in either Chrome or Edge, the PDF opens properly which leads me to believe the problem is in Firefox and not my Adobe installation.

Thank you

IME toggle not working in youtube chat on Firefox, even in troubleshoot mode. It works in all other applications including Chrome browser yet I prefer using Firefox so hope issue can be solved.

Every other day, I open FireFox and may get the following error: XULRunner - This profile was last used with a newer version of this application. Please create a new profile. Also, this error may come up while I already have had FireFox open for a while. Once this error comes up, I check the version, and sometimes the version is older than what it was, meaning, FireFox reverted back to an older version on it's own. I created a new profile, but the error comes back. I removed FireFox and all folders, and the error still comes back. There is nothing I can do to stop the error from showing up again. See attached images. I am on Windows 11 23H2, all windows updates caught up, and the current FireFox browser version is 138.03.

When I'm on a website and click on a link to open in a new tab, the new tab option does not show. The open a new window shows. The options should show in the order of open a new tap on top, followed by open a new window. This only happens when the link shows above two third's of the page. If the link is on the bottom third of the page the option for open a new tab shows above the open a new window. When on a web page I can't scroll down if the link is above two thirds of the page (at the top two thirds of the page). This has been happening through Firefox updates that don't correct this issue.

Why am I receiving repeated warnings from Malwarebytes about blocking every-day websites due to a "Trojan"? The sites include Gmail, Ancestry.com, Newspapers.com and others.

The report warnings are being generated by the Malwarebytes program on my PC. They are confusing to me. I am running Windows 11. The warnings are being logged by the Malwarebytes program in the "Web Protection" section of its "Detection History" web page. In every instance, the log reports are the same: in the URL identification column there is no identification of the URL, only repeated instances of "N/A"; the IP address is identical for all the warnings; the port is always "0"; the file column alternates from "C:\Program Files\Mozilla\Mozilla VPN\Mozilla VPN.exe" to "System" and back again to "C:\Program Files\Mozilla\Mozilla VPN\Mozilla VPN.exe"; in the final column of the log, the Date column, the warnings began last evening, Monday the 12th, at 6:50 p.m. and have now extended to to a total nine warnings.

Even as I was writing this communication, the Malwarebytes warning popped up on my screen, telling me that this website and this web page are blocked due to the presence of a Trojan.

Is my PC infected? The Malwarebytes "scan" reports no "detections." I am at a loss.

I've asked about this before but got no help Firefox is my browser of choice. Occasionally, I find in necessary to use Chrome.

The vast majority of time, when are both are active at the same time, one or both crash, like today. Firefox closed abruptly, then the crash report appeared. I have the crash report. Chrome froze up, and had to be shut down in Task Manager.

It only occurs in this scenario. Rarely does Firefox crash otherwise.

Can someone please advise where to go to get help?

Tabs can take up a lot of space, 1-2 gigabytes if you don't watch. That really slows down the browser. Seems to me that merging tabs will, if you aren't careful, seriously slow the computer. Comments?

According to the most recent update page, this function should be working for all users by now. (see attached screenshot).

It is still not working for me. Has the timeline been postponed? Is anyone else still unable to use this function?

Thank you!

Hi!

My Quickbooks online account is running ridiculously slow in Firefox. I have exhausted all avenues to troubleshoot with the Quickbooks team. Their advice was to switch browser to Chrome which did resolve the issue however I do not want to use Chrome. Can you offer me a solution of how I can effectively use Quickbooks without delay while still using Firefox?

Thank you!

My laptop (a Lenovo Ideapad220s) did an automatic Windows 11 update (I believe it was the 2H24 update). After that Firefox (version 133, 64 bit) would only open with the message "Gah. Your tab just crashed". Nothing I tried has worked, not any of the remedies found in support pages. I somehow did a Firefox software update and it shows as a separate icon and has not migrated any of the passwords and bookmarks I had in the software version that keeps crashing (my default browser). Trying to get access to the encrypted passwords to the many sites I've got with Firefox I opened the browser in troubleshooting mode. In this mode I have access to all the passwords saved over time, and the browser seems to work fine.

Any suggestions on what I need to fix or if this is related to the Windows update? I'd like not to have to go through the two-step process to use the browser.

Thanks!
