Although I use dark mode on my mac, I have firefox set to light mode theme, which pretty much works for the tabs and such. However, when I go into Preferences, the theme is dark and, for instance, if I want to search my cookies/cache to specifically remove some of them, the black font on top of the black entry field makes it impossible to see what I am typing. Is there any fix for this?

I have persistent spam-ware type download that wont go away. I have deleted it but every time I restart Firefox it comes back and pops up saying "This File may harm your Computer" but i can't complete the download or remove it permanently. i have tried uninstalling and reinstalling Firefox several times and it has not worked how can i get rid of this? Thank you OSX Firefox V87.0 64-bit

I visit sites which require password changes on a regular basis and each time I do this I save the login details in Firefox.

Now I have sites where over 20 login options are displayed.

I want to delete all of the expired login combinations but when I try to manage the passwords I only have the latest (correct) combination displayed.

How do I prune my password lists to remove obsolete details but retain the current ones?

Can this be done by exporting the list, editing it externally and then re-importing? I don't want to try and then lose this useful feature.

I recently opened Firefox and it prompted me to create a new profile. I closed it up and reopened it 2-3 more times and it did the same thing. I created a new profile. My bookmarks immediately disappeared, and so did all of my old profiles. I have tried many online suggestions for restoring both. Firefox is up to date, and Windows has been recently updated too. I have an older (2013) Toshiba laptop. Any suggestions?

All of a sudden I can no longer access silverdoctors.com. Until very recently I was able to access on both my PC and my laptop, and now can no longer access either. No other changes of which I am aware.

Any help is appreciated.

Hi, I am having a bit of an issue when it comes to syncing my passwords, logins etc from my windows 10 laptop to my Samsung S21 phone, Not all my passwords, logins are there on my phone, yet they are there on my laptop. I am signed in to my phone and I have synced everything. And I do it regular to make sure I have all my details etc that I need. I have the very laterest versions on all my devices, so I don't get why they aren't there on my phone?

I am trying to minimize Firefox, but the minimize icon in the upper right-hand corner is missing. I am still able to close Firefox using the 'X' in the upper right corner of the window, but I am unable to minimize or restore. All other applications still have these icons available.

Dear Mozilla firefox Community,

1. My computer is a new HEWLETT PACKARD. It works beautifully.

2. WINDOWS 10 HOME. No problem.

3. Here is the strange occurrence. With MOZILLA FIREFOX I have in the LANGUAGE SETTINGS, chosen for now, only four languages: ENGLISH UNITED KINGDOM, ENGLISH UNITED STATES, FRENCH & ITALIAN. I may in the future also add GERMAN and SPANISH.

4. The main language highlighted is ENGLISH UNITED STATES.

5. I also have chose the CHECK SPELLING in the little grey window if there should be a typing error. This and all of the above I've set also with my GOOGLE CHROME browser, except the term used with it is ENHANCED SPELL CHECK.

6. I have four mail servers: GOOGLE, HOT, YAHOO & VERIZON by way of AMERICA ONLINE.

7. Here is the problem with MOZILLA FIREFOX that does not occur with GOOGLE CHROME: With CHECK SPELLING clicked-checked on, all of the languages will result error with a red erratic line underneath them, even if correctly spelled. Sometimes an American spelling will have it, apologize, sometimes a British spelling, apologise, and not the other, and sometimes both. Likewise with French and Italian. I may type one message using all four languages, and errors for all.

8. If I compose an electronic mail message using GOOGLE CHROME, whether with one language, or I type it using words in all four languages in one message, if the spelling is correct there is not a language error red line. Only when I misspell a word in any of the four, this is what is supposed to happen with MOZILLA FIREFOX, but it doesn't.

9. With MOZILLA FIREFOX, I must unclick the CHECK SPELLING to avoid the red line errors,Yet, I won't get a red line error if I should indeed type a word wrongly. With CHECK SPELLING even correctly spelled words in any language result red line error!

10. Why is this taking place? I have correctly chosen the four languages, chosen United States English as the main language for MOZILLA FIREFOX browser. This never happened with my DELL INSPIRON computer and WINDOWS 7 HOME. Please understand I am not computer savvy, and I dread something goes askew with the computer settings. There must be something that is being overlooked. I await your kind and patient assistance. Eric Galati

Recently, I opened up the Firefox browser and it prompted me to create a new profile. I reopened the browser 2-3 more times and the same thing happened. I created a new profile. My bookmarks immediately disappeared. When I went to look for my old profiles, they all had disappeared, also. Firefox has been updated recently, and so has Windows 10. I have an older (2013) Toshiba laptop. Any suggestions for getting profiles and/or bookmarks back?

Don't want to use either option advised by bank.

Using Firefox 68.12.0ESR. I know 78 is available, I just haven't had the time to test it yet. I delete cookies when I exit Firefox. I want to keep some for sites that I trust, such as this site. I've added exceptions to Allow these trusted sites as documented on a thread somewhere else, but it doesn't work. All cookies are deleted.

Is it possible to keep cookies only for a select group of sites. eg. support.mozilla.com, tomshardware.com, mydigitallife.net, speedtest.net and so on.

Thank you.

I followed cor_el's advice and created a new profile. This helped me for a while (i.e., I could delete bookmarks duplicates), but it stopped working. I tried creating another new profile, but it didn't help at all. Since a new profile doesn't seem to help me (i,e., I still can't delete duplicate bookmarks without all copies disappearing), does anyone have any other suggestions?

Thanks.

I reformatted my laptop and reinstalled Firefox, and now certain parts of webpages are not showing up. For instance, on answers.microsoft.com, I cannot see "reply" boxes so I can't post anything. on homedepot.com, I can't see the tool that tells you the location of each product and allows you to text it to your phone. The webpages look "normal" except that the missing content is just... missing. I'm wondering if content is being blocked on other websites, too.

The websites appear correctly if I clear cookies and site data from Firefox, but not if I just clear the cache. The issue appears in "safe mode" also. It doesn't matter how many times I restart my computer-- the issue is still there. I have as much of Windows Firewall blocked as I am able to. I have uninstalled my ad blocker extension. The website page style is "Basic page style."

This is so frustrating. Please help.

I've been getting security warnings from my security software "Bitdefender" for firefox. Bitdefender is giving me warnings about "suspicious connection blocked" for "gitcdn.link" within Firefox as an "Online threat prevention". Word for word is as follows "Suspicious connection blocked. Feature: Online Threat Prevention. firefox.exe attempted to establish a connection relying on an unmatching security certificate to gitcdn.link. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one." First: I did not access "github" which "gitcdn.link" appears to be linked to in accordance to a general google search. Second: This warning appears every time that I begin using firefox as well as periodically while I am using firefox. Third: in my process of trying to report this problem mozilla.com directed to a "support" website that would not take my mozilla firefox log in while it had a box stating to "sign in with github". I'd like to know if mozilla uses the "gitcdn.link" in it's firefox browser in some way? And if so, I would like firefox to corroborate with bitdefender to resolve the security issue. If not, then I would like a way to get/have a clean firefox browser that doesn't continuously get seecurity warnings relating to firefox and it's operation. Please help

Hi all, I have an Apache site on Kubuntu 20.04 with a certificate signed by my private CA. I've added the root CA ceritificate in Firefox and in Chromium.

Firefox throws a SEC_ERROR_BAD_SIGNATURE error

Chromium accept the certificate as valid

What can I do?

Notes: the site url is "https://hdev.h.net" (with an internal IP address inside my lab)

Attached there are:

- the authority settings page
- the certification authority certificate as seen by Firefox
- the site certificate

Firefox version 82.0 Ubuntu Chromium version 86.0.4240.11

When Firefox is open and not minimized, GPU usage for Desktop Window Manager will go from around 0.1% to around a constant 25%, and when Firefox is maximized, will go up to a constant 55%. "Service Host: GameDVR and Broadcast User Service" GPU usage also seems to go up but not as much.

This doesn't happen with other browsers I've tried, the GPU usage of Desktop Window Manager will go up but only for a second then go back down again.

I've attached images of task manager when Microsoft Edge is open, when Firefox is open, and when Firefox is maximized.

After you install a firefox update, a page loads. Sometimes this page distracts me and I forget what I was opening the browser for. I don't care what's new even a little bit. If it was that important I'd have heard about it already from one of the news sites I visit. How do I stop the page that gives you information on the update you just installed from loading after I update the browser? I don't need to be advertised to, I already installed the update.
