Firefox Support Forum

I have reinstalled and refreshed the app many times, but whenever I try to search something, it says "An error occurred during a connection to www.google.com. PR_END_OF_FILE_ERROR. This happens with every single search on every website, not just google.

When I access bookmarks using the manager/editor I see all bookmarks. However when I try to use bookmarks from the dropdown in the toolbar, I only see some bookmarks. I think it's the newer bookmarks that are missing but not certain.

You search for a word using Control+F like any other program. It's highlighted on the page if it's there. Or you would think so. But no. Why does Firefox so often say it found a word when you can clearly see it's not there on the page? Nothing is highlighted. It even gives you the number of results on the Find bar. Some may be there but others are not. This has been like this for years. Why?

Just downloaded Firefox a day ago; since a friend told me that its better than Edge. It seemed fine at first and then went and looked at task manager. It's using way more memory than Edge. Firefox has 19 separate tasks running totaling to ~1,500 MB. I need to know what I can do to lower it. My friend made it sound like Firefox was way less memory intensive. I don't even keep 10 tabs open at a time. Any help would be appreciated.

I am unable to login to the DVLC. I get as far as the enter reg number of a car to check it,s been taxed. Then after I input the reg number the next page tell me it is an insecure page. This also happens on my laptop. On both desktop and laptop I am using firefox with duck duck go as an add on. However. In using my mobile with the stand alone duck duck go browser, I can log in and complete the task. This points to a problem with Firefox. Any advice's. This seems to be recent as I have used the laptop and desktop to use the check for a taxed car system ok in the past.

Often, when I go to a website with a store, a website called "coupon2deal" (coupontodeal.com) will pop up. It will be at the beginning of my list of tabs, and it will have a miniature tab with no exit button (I need to right-click it to exit). I believe this may have started after I installed the Honey extension, a similar service, but it has not gone away after uninstalling Honey. I tried blocking the site, but the tab still pops up, just with the website blocked.

I have spent hundreds of hours over the years trying to figure out how to hell to suggest words to the default firefox dictionaries. I don't mean weird words, words used constantly in scientific settings. It is infuriating. I am willing to take on this task if no one else is. How do I join the effort?!? I have 20 years experience at a fortune 500 company. Google is worthless these days.

I have two end users that are having a different issues but they are of similar nature. First user can not upload anything to Microsoft Share point. She gets a message that says she does not have proper permissions to upload. She does not have the same issue on Chrome or Edge. The second user is trying to download and or save a file from a couple of different websites but regardless on where she tries to save it on her computer it says she does not have proper permissions to save to "x" file location. She also does not have this issue when she is on Chrome or Edge.

For both users I have tried clearing cache and cookies, Rebooting their computers, uninstalling and reinstalling Firefox, deleting registry keys/user data from the computer itself. I have had no luck with resolving this issue and I can not find anything online that remotely resembles this issue.

Thank you and please advise

Firefox is telling me I can't use the JUB site because it's embedded, I don't know what that means? I've been using the site for over a year and I've never had a problem with Firefox. All of a sudden I'm having issues. I want to resolve this because I want to continue to use this site.

Hey guys, thanks for the help in advance.

This problem occurred recently and it's quite a pain in the ass. I'm using Macbook Pro 14 inches with M1 Max chip. Lately when I work, I have to open quite many urls at the same time, and my mac went crazy hot because of firefox's insane cpu usage. I tried what's suggested to turn off the acceleration mode, but still, nothing changes.

Is there still anything I can do to resolve it? or I just switch to other browser?

Last months problem with Firefox, one process goes to 11-20% cpu usage+-, firefox does not load sites, freezes, after some time works again. Tried every solution and nothing. I have to wait or restart Firefox. I have similar problem on Android and notebook from work. You are unable to fix your browser but you complain that that MS, Google and Apple block independent browsers. Maybe the way to fix is reinstall Windows. GO TO HELL!!!

I have attached images of what slowly occurs when I don't clear my cookies, websites start to slowly and slowly load less and less until they eventually completely break and wont load and I have to clear my cookies, resign into everything. and rinse and repeat every few days or a week, I also attached an image of what the purchase screen is supposed to look like. Looking at this via Microsoft edge

ty for your help the lastest MS update 2 days ago12/13/23 on my pc is preventing me from opening firefox regular or private browser. I downloaded new firefox intalled same results. i have other friends who had this happen to aswell and thought for sure ms would fix or a fix would be on this site. so im surprised on no posts. must be millions of us out here in the dark. please help david

I am having a problem with my Firefox homepage. There are several things going on like the red, yellow and green dots on the left side of the menu change to light dark. Some of My Bookmarks appears twice and one was added. I did a Refresh and troubleshooting but to see if my home page would go back to normal but it did not. I think I have a bug that is causing these changes on my Mozilla Browser. I need to get the browser back to normal.

I am trying to find answers in relation to my Favourites shorcuts not showing the Icon for some well known websites e.g BBC World News, CNN. Once answer found on the Firefox Forum is: Make sure that you allow pages to choose their own fonts.

Tools > Options > Content : Fonts & Colors > Advanced: [X] "Allow pages to choose their own fonts, instead of my selections above"

This is just typical of many answers I find on the Firefox forums whereby the suggested solutions seem to bear no resemblance to my Firefox system. Am I using something different? Everything points to me having the latest up to date version of Firefox. For example if I click on the four horizontal line hamburger on top right of the screen I do not see anything that begins with "Tools" in the menu options. I see "Settings" and "More Tools" but none lead to "Options>Content: Fonts & Colors> Advanced: [X]. simarly, If I click on "Tools" in the menu at the top of the Browser nothing leads to "Options". Any suggestions please?

Ever since the automatic update of the new Firefox 120.0.1 none of my pages or websites will open. No matter where I go I get the error message: Error code: SEC_ERROR_KEYGEN_FAIL before the update I was able to open my bookmarks and other websites with no issues. It is now totally unusable. Please help I like Firefox over Chrome and Edge.
