Firefox-Hilfeforum

I have a recent problem with mouse hover with Bookmarks in the Menu bar. Basically; it no longer shows the URL info in the drop down box, only a blank, box appears. I am using Windows 7 and the current Firefox 107.0. It appears to be a Windows 7 issue, because I have the same problem on my Win 7 desktop and Win 7 laptop, but a laptop with Windows 11 is OK.

The really odd part is this. If I run Firefox in troubleshooting mode in either Win 7 machine, the problem goes away, and the drop down box works fine, and displays the URL info. If I manually disable my add-ons in normal mode on either machine however, the problem does NOT go away.

One last odd point. On my desktop, when I am in normal Firefox mode, and look at Bookmarks in the History tab from the menu bar, the last (bottom most) bookmark, and ONLY the last bookmark WILL display the box info correctly. On my Win 7 laptop the same effect occurs, but the last (bottom most), bookmark will sometimes work properly in other folders, such as Other bookmarks for instance.

Also; the URL box does work properly with the ‘Show your bookmarks’ button, and the bookmarks menu if I use the “Open application menu”. These options produce too much ‘white space’ however, and are not as convenient to use. The drop down box works fine with other browsers, but Firefox is my favorite browser. I have searched the Internet and the forum, and not found a similar problem.

Attached are two photos showing the result in normal and troubleshooting mode. Thank you in advance.

Dear Sir I had been watched youtube many years, but a few years back then it kept signed me out, and I have had to sign in again every time. It's annoying and rather fed up too. would you help and give me advice how can I stay sign in once and for all. Thank you. Regards. Louise

After moving to Firefox 91.9.1esr I found problem with System theme 1.2. The color of tab add button was changed, and the button is not visible with my Windows 7 classic windows system theme. So, I'm trying to find a way to port System theme 1.0 color scheme to newer firefox versions.

Creation of a simple theme with firefox color extension works. But it is unable to recreate the effects related to active and inactive window color changes. As, I had to use bitmap to get the OS blue color transition pattern.

It seems the system theme is stored in omni.ja file. Modification of the omni.ja seems to be not a practical solution. So, it would be a better way to create an addon theme with the same code as the System Theme 1.0.

The first question is, if it will be possible to create a theme with the same code as a system theme has. Will it be able to perform the same way?

The next question is: Where the source code of the system theme is? I was unable to find it in the Firefox source. It seems, it is not stored in any obvious location.

Problem I had two versions of Firefox open. Window "A" (my primary window) had many open tabs. Window "B" had only three tabs open. Like a knucklehead I accidentally closed the wrong window, "A". Upon restarting only the "B" version was there.

Possible Solution Two days ago I cloned my "C" drive as a backup. Although the Profile folder on the backup will only have 90+% of the tabs - I can gratefully live with that. I just need to know what files to copy over from the backup drive Profile folder to the messed up drive's Profile folder. I am hoping it will be that easy and I can copy the tab files and not the entire Profile folder. Thanks.

Previously visited links of eBay items are not showing up in "purple". eBay has increased the length of those links beyond 255 characters which seems to have triggered this issue. I can click one item on a listing search page and it will be purple as long as I open a second tab when opening it. But when reloading the same list, the same item is not purple as they always used to be. Actually, a few still are, and those have the shorter URL. The links do show in the history record. This is very annoying, I can't imagine I am the only one who is finding this. It has persisted through the last two updates. This needs to be fixed.

Hi, we have 4 PCs (3 running Win 10 and one Win 7) which updated themselves today and lost everything. Settings, add-ons, bookmarks, shortcuts all gone; looks like a new install. I checked the other threads and the profiles; there is only one profile and no backup. How to get my stuff back?

bold text I am on windows 7 because 10 not working. I went into Facebook chat and trried to do a wecam in the search box in messenger in facebook I can see me but can not see the other person it says g he has joined but i can not see them works in Chrome I tied disableing all my extemntions and turning off everything reinstalled the camera reinstalled forefox and can not see the other person

First, this post is basically Congratulations for Firefox upon working almost flowlessly under this extreme heavy load without crashing. Saving/loading sessions works well. (which is unexpected but makes me _very_ happy :-)) Firefox exits properly without any exceptions, no matter how long it runs, or how many times the PC is sent to STR mode meanwhile.

Second, everything is fine, except RAM usage. No matter how many RAM is installed, Firefox takes up all of it after a few days of normal operation. I have recently upgraded my PC from 16 to 24 GB of RAM only for this sole reason to see if anything changes, but it did not produce any noticable change, except that it takes 5-7 days for Firefox to fill up all the RAM instead of the 3-4 days before. Disk space on C: drive was nullified by Firefox as the paging file went up to 50 GB.

I want to hunt down this thing. I have approx. 300 tabs, 2 addons, and Hardware Acceleration is disabled since otherwise Fox hangs several times a day (have to be killed from outside). Pics are attached. https://addons.mozilla.org/hu/firefox/addon/tree-tabs/ https://gitlab.com/kroppy/TreeTabs

I'd like to get suggestions where to start.

1. Disabling or replacing the adblocker ?
2. Inspecting memory usage on Process Manager (about:processes) and Task Manager (about:performance) pages ?
3. Installing some external tools like Firemin ?

Please don't suggest neither safe mode nor disabling all addons, since that makes it impossible to reproduce this amount of load, which is the primary reason behind the symptom.

I PrtScr'ed Process Manager and Task Manager, see that RAM sizes per page are normal in Task Manager, but not in Process Manager (10 times more).

CPU usage is totally normal for this load, even when memory is in the heaven. See the TaskMan pic. (I suppose that's because of ad blocking)

Thanks for any ideas,

Peter B. (I'm PC enthusiast)

Twitter Video Streaming in Firefox on an older computer (Windows 7) does not work. The videos don't play (just audio). I logged into my same Twitter account on Chrome on the same computer and Twitter video streaming worked perfectly. Please fix the disparity.

Everytime I try to close my Firefox browser window, it just stops. There are multiple processes taking in excess of 200 or 300K in memory that seem to be causing the problem. I have to manually end the process just to close Firefox, and it is quite annoying.

I just checked, my Firefox is up to date. Yesterday I deleted and re-installed Firefox, but it's still doing the same thing.

This is kind of driving me nuts to be honest. I have Chrome, Opera, and Edge also installed on my computer so I'm ready to jetisson Firefox but thought I'd see what the community has to say first.

1. I'm using Firefox portable latest version.

Nearly all addons stop working every time I restart Firefox. I have to manually disable and re-enable each addon to make them working again.

It takes considerably long time the first time I load the first website after I restart Firefox. Also it may suddenly hang after using for a long time.

What's up? How could I fix them?

2. I would like to transfer all settings, cookies/local storage, addons (settings and files etc.) to a fresh copy of Firefox portable, to see if those issues would be fixed. What should I do? Which files do I need to backup?

Thank you.

For the last several weeks, the reliability of Firefox has went off a cliff following an auto-update. After a few hours of browsing, it gets to the point where the tabs load extremely slow (or not at all). When this happens, I exit and relaunch.

Previously, it would be nearly instantaneously where the windows would close and the firefox.exe process would cease within seconds. Now, it's taking upwards of 5-10 minutes for the process to stop AFTER the windows have closed and, during that time, it'll bring the system to a near crawl. Once the process finally closes though, everything is back to working fine.

Currently my firefox has many userids stored. I want to delete **EVERY** single one of them **IN ONE SHOT**. How can this be accomplished?

Before answering, please note the following:

1) I do not want to use the SHIFT-DELETE trick. Why? It's a lot of userids. It would take too long, some would get missed. I want to delete ALL of them ALL AT ONCE for EVERY website.

2) The Saved Logins screen doesn't work. Why? Boy that's a good question. Apparently the Saved Logins screen only saves userids if you've also allowed it to save the password. I always decline when firefox asks to save passwords, and thus, when I open this screen is says "No logins found".

3) Clearing cache and cookies does not work. After I do that, those logins are still suggested to me.

4) This has nothing to do with being sync'ed, as I never login to firefox to use their browser. Never.

Any ideas?
