Firefox Support Forum

In Firefox 115.8.0esr on linux RHEL7, I am loading a local html page (using file:///...) that I created. Inside the html page, I have a tag "<object id="hiddenDataObj" data="abc.txt">" where abc.txt is a text file in the same directory as the html file. Using my default profile, the data is loaded and some downstream javascript runs as expected. When I use an alternate profile and try to load the exact same page, I get a javacscript error "Uncaught TypeError: hiddenDataObj.contentDocument is null." It is not null when I run my default profile.

I'm trying to figure out what setting in my profile is enabling/disabling the loading of the data so that I can change it. I've gone to about:preferences and scrolled through and it seems like all settings I see are the same between the two profiles.

Thanks for any help.

When opening a private window after the 127.0 update, now opens opens a new window on the far right. It is no longer connected to the FireFox browser. In about:config I have it set to False for browser.PrivateWindowSeperation.enabled. That worked in the past but doesn't seem to be working anymore.

Just today when I opened private browsing tab on my firefox it opened a new separate window and an icon appeared on the taskbar unlike before where the private window would be one with the firefox icon on the taskbar. I tried the fix of editing the config browser.privateWindowSeparation.enabled and turned it to false but still it did not work. I also disabled all my studies but it still is the same. I have attached several screenshots about the problem and solutions I tried.

This morning I saw that images were not downloading within my GMAIL messages. Believing that something was wrong with my connection, I decided to give both my computers a restart. This concerns my Windows 10 64-Bit, on which I had both Edge and Firefox opened, both with multi-tabs. In Firefox I had my Google account open with other tabs. After shutting down both computers I left my apartment. The Windows 10 restarted on its own; but both browsers lost their tabs even though I set each to reopen the previous session. With Edge and function keys I was able to restore my previous session; but not with Firefox. about:sessionrestore was not available. The Profile folder did not show a backup for these lost tabs. I hate hunting for them in History because I am working on multiple projects and don't have time for this wasteful activity, which is why I set Startup to Open Previous Windows And Tabs. What option did I miss?

Now, we have more wasted time. I reopened as many tabs as I remembered opened during the session I could not restore. Now, the only tabs that reopened since are the ones I opened that have posts about restoring sessions. The tabs I reopened are lost even though I checked off Open Previous Windows And Tabs. This browser is performing worse as of today for some reason I am not aware. What changed? From what I see here, there was no MS Windows update that might have occurred when I shut down and lost the tabs. Could I have disrupted the tabs by using the right hand, top corner "X" to shut out of Firefox?

This is getting more and more whacked up! It seems that every time I reopen a tab within the Library, it opens it in the same tab, overlaying the previous tab I opened.

I have a site where I have a valid login and password. I can login in Edge and FF Private Window, but in FF I get the attached message. Coninued tries gets me locked out for 24 hours.

I have whitelisted the site. Cleared caches and cookies, etc.

What does this mean and how can I fix it?

Thanks!

SLES 15.5 QU2 in Mozilla Firefox 115.8.0esr was not supporting window.close() even i added user_pref("dom.allow_scripts_to_close_windows", true); in user.js and prefs.js

All of a sudden, I can't download any attachments, no matter what file type it is. I've reset Firefox to it's default, restarted, everything suggested. I don't have the first clue as to what this is.

Every time I sign into something using Firefox the recaptcha does not allow me to continue. If I switch to Google Chrome it works. Please help me to be able to use Firefox.

When downloading a file in Facebook Messenger, Firefox changes file extension to .pdf. My case was .docx file but looking for help found people have problem with other formats, even non document saving as .pdf.

Not asking for help, just reporting problem

There is a hacker who accessed my Google account via Firefox about 10 hours ago, with the result my language setting has been switched to Korean. I live in Hong Kong and have never been to Korea, and I do understand Korean at all. Can you help pls? Thx.
