Firefox Community Forum

In case anyone's interested, under Debian 12, when I resume from hibernation, if I have Firefox running as well as Tbird, if I click on a link in an email, the existing instance of Firefox is ignored and a new instance is opened. The first instance is in fact frozen -- it looks as it should but trying to change tabs or open a new tab is inactive. Seems I have to kill the open instance of FF, then if I click on a link in an email, FF pops up as it should with a new tab for the link, but the existing tabs are all there and all functional. It feels like a bug -- Tbird seems not to know that FF is already running.

a web site continues to say mozilla browser need update to correctly access web page. I have downloaded latest update ESR for Firebox (using windows 7 OS) But web site still says I need update! Is it me or the web site that has the problem?

When reloading a page, or navigating to a new page, the default Stop icon momentarily appears over my own Reload icon, and the default Reload icon also appears over my Stop icon.

Please see attached image and animation.

Any idea if this is a minor bug?

Below is my code to split the Reload button into Reload & Stop buttons, then to add text to the navigation buttons, and finally to add icons to the navigation buttons.

This anomaly happens whether or not I split the Reload & Stop buttons. With just a single Reload button, I'm also seeing the default Reload icon appear over my own.

Thank you.

I am running macOS 10.15.7 and Firefox won't upgrade past ESR v. 115 to the "regular" version 127.

Alternately, downloading the Firefox v. 127 installer and running won't update ESR v. 115 nor will it import bookmarks or data from the previous version ESR 115. Firefox v. 127 installs and starts as if I am a new user without any update or import option so that all previous settings, passwords, and data from ESR v. 115 are lost.

Is there a work-around for the upgrade to keep continuity, settings, bookmarks, and data when migrating to v. 127? Thanks!

After updating a W10 laptop from 115 to 116 of FF the user started having problems with getting to different websites (sites they worked on/with regularly). The problem is the cert DB. The doc I found says that it is cert8.db. Actually it is now cert9.DB.

What I had to do was go to task manager and kill a task that was holding the cert9.db file. Then I could rename it (cert9.old.db). Then restarted their laptop and FF came up and started fixing the cert file (as expected). This seems to have fixed their problem.

Dear Ty: I appreciate your efforts to help me, unfortunately, it did not work. FireFox is still at 115.30.0. Any other thoughts?

I thought there might be some software I could download to spoof the Chase system into thinking Firefox was a later version,

Thanks and regards,

LS

Recently upgraded to windows 7, and upgraded firefox to version 115. Why am I getting notices that Windows Vista is no longer supported. [upgraded from vista to 7]

The spell checker isn't working for me. I've found old answers to this:

"You can see which dictionary is selected if you right-click in a text area and open the Languages sub menu. At least one dictionary should be installed and have a check mark to indicate that it is selected.

   open the "Add Dictionaries" link to install a dictionary if you do not have one. 

The spelling checker is enabled if [X] "Check Spelling" in the right-click context menu has a checkmark.

You can enable or disable spell checking globally:

   Options/Preferences -> General: Language and Appearance: "Check your spelling as you type" 

You can look here for dictionaries:

   https://addons.mozilla.org/firefox/language-tools/ 

Note that for spell check you need a dictionary. A language pack provides string translations for the user interface.

   https://support.mozilla.org/en-US/kb/use-firefox-interface-other-languages-language-pack 

You can check the layout.spellcheckDefault pref on the about:config page.

   http://kb.mozillazine.org/layout.spellcheckDefault "'

But I don't understand what most of this means!

I don't find 'language' because I don't know where to find a "text box containing more than one line" I'd have thought this was one, but the option does not come up here when I right click.

I realise this is probably me being dense, but can someone help in simple terms, please? Thanks.

why everytime i use firefox the default web address is: https://hao.360.com/?src=lm&ls=n077c1cd59a

I just tried to open Firefox and got the message "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem". DO NOT redirect to this link

https://support.mozilla.org/en-US/kb/fix-bookmarks-and-history-will-not-be-functional?as=u&utm_source=inproduct&redirectslug=The+bookmarks+and+history+system+will+not+be+functional&redirectlocale=en-US

It is useless. I tried to restore 3953 items from a previous back up and received the message "Unable to process the backup file".

I am not interested in hearing how to prevent this problem in the future, because obviously creating backups do not work.

How do I check to see if the problem was caused by security software, even though I have not added anything?

In numerous cases i have found not to be beneficial when website's search function is activated on Ctrl+F keyboard shortcut and where is better to use regular Firefox on-page search instead. I think that the good site has search button/area visible so i can use it when needed.

So please how to disable Firefox's search (Ctrl + F keyboard shortcut) to activate website's internal search? I want to always use regular Firefox on-page search that i now trigger by left Alt (to show the FF menu), click Edit menu, click Find in page.... (since Ctrl+F is occupied by website's internal search).

I have a Plesk (apache) server that is behind HAProxy. When I connect securely to a web site through HAProxy using Firefox, I get long delays. If I use Safari or Chrome, the pages come right up without any delay.

If I connect to the Plesk server directly without HAProxy in the middle, there are no delays.

I do not know what would cause these delays that don't occur with other browsers.

I'm on a Mac: 115.0.2 (64-bit)

When I try to sign in to Chase banking, it tells me to upgrade my browser, which I have already done. Had to use Edge to login successfully. Using Windows 11 Pro with current Firefox browser.

Is this 115.32 still in effect for my macOS 10.13 ? Or is it xld as it would be in Feb 2026?

Did or does Firefox 115.32 afford my apple macOS 10.13 enough security until I purchase a new computed.. How much more time do I have.

Hopefully you can help. I know this may be a Microsoft issue or question but I'm having trouble in finding a reasonable way to contact them for help. My question is, my computer runs slow, and so I thought I would clean up my files by using the Microsoft disk clean up procedure. I did so. But, my specific question is what is a good number to have when the it says a given number of disk space can be cleaned up? For example, I believe when I first tried to clean the disk it said 5.1 GB of disk space could be cleaned. When I ran the disk clean process and it completed it then said 66 KB of disk space could be cleaned. So how much disk space did I gain or get cleaned up? And, if I can only clean up 66 KB of disk space is that indicative of not really needing to clean the disk any farther? Hopefully some one can help. While this may be a Microsoft issue, I believe the Firefox contributors have enough computer knowledge to help answer my question. At least that is my hope. Thank you.

I still have not had any improvement with tab crashes especially on sites containing videos. Lately, every time i go on Facebook and play a video reel, i stop the video and before i can return to my home page, the tab crashes. This browser has gotten worse rather than improving.

Hi.

Whenever I click a button on the keyboard, the CTRL+F function comes up on it's own. I had previously disabled it because it ruins all shortcuts on youtube and with tourettes, I often also get thrown around if I am reading long articles, because of misclicks.

Unfortunately I did the big mistake of updating, also with a tourettes-missclick, so my question is: 1) How do I remove the 'quick'-search function? I want the Ctrl+F bar to come up ONLY WHEN I CLICK ctrl+F, and I want it to go away again if I click ctrl+F again. I forget how to do it. 2) How do I remove all future update prompts? Given that it has been made so hard to configure firefox into something tolerable, I don't want to throw all my setup away with minor updates always thrown at me. It takes me a long time every time there's an update, I have to fix language and other stuff back again. It's just not worth it in time for me to use Firefox, if I have to make a setup so often. 3) Recommendations for the best version of Firefox to go back to and stay in for eternity, alternatively, browsers that does not change or add functions without first asking the user... (The answer is no, by the way, I don't want more new fancy functions)

Sorry for this nagging but I simply can't use my browser like this. It's just not working.
