Firefox Community Forum

i have two computers. on computer 1, all is fine. on computer 2, when it restarted after an update, i got the error message -- "the bookmarks and history system will not be functional b/c one of firefox's files is in use by another application, some security software can cause this problem." this has NEVER happened before.

i found the "how to fix this problem" page, but i am completely baffled by it. what i want to know is what security software (i have avast apps) is likely to have caused this problem, and how do i fix it (i.e., what setting should i change?).

thanks for any help you can provide. i am NOT tech-savvy, this is the only time this has happened, and i've had both computers for years. they have both always had the same apps.

Hi guys, Just wanting to know why the Captcha is so hard. I sometimes need to do the captcha 30-40 times. Can't there be a simpler way to do this. it's very frustrating when I google an address that I need to go to but it takes 15 minutes to get through the captcha. I end up closing Firefox & opening Chrome or Edge. Can something be done about this? Also, Captcha is not clear.. When it comes up with "Motorcycles" is the rider included in this? Or "Stairs" is the hand rail included in that? Please change it to make it simpler so I can continue using Firefox. I'm using Windows 10 on a computer.

Thanks guys

Hello, This is on Win 11, always latest updates to win and FF.

For at least the past 9 months saving anything (web pages, files, etc.) is incredibly slow. I have filed bug reports but nothing back. After starting the save the wheel rotates for 1-2 minutes before finally waking up and saving. FF is completely frozen until its done.

On a second win 11 box, the download are fast but flagged as download failed but the file was actually downloaded

Anyone know anything about this? Like why or how to fix it.

I'm switching to Chrome until this is resolved but I hate Chrome so I hope it will not be a long wait.

Thank you all

Why does attempt at loading a UK Government web page (https://vehicleenquiry.service.gov.uk/) produce a "Secure connectionn failed - Error code: PR_CONNECT_RESET_ERROR" message?

I managed to load the same web page by using Chrome.

Hello guys,

The trouble I ll present you might come a bit late, I've just never thought about asking on this forum (didn't even know that it exists lol) and I spent a lot time on tutorials trying to find the solution... lol 😩

My situation : I have a laptop with debian 12 stable. Early July, I updated my apps, Firefox 128 has just been released. Since the Firefox 128 update, I can no longer execute Firefox, I always get the pop up message :

Failed to execute child process (no such file or directory)

I've tried many times to uninstall & reinstall, purge & reinstall. Still the same "failed to execute... " message. all the subsequent updates (128.X and 129.X) haven't solved this problem...

On the other hand, Firefox ESR 128 works like a charm.

Is anyone in the same situation as me ? 😕

Wishing you a nice day :)

Firefox freezes intermittently, and when I examine the situation with Windows' Task Manager, I see a large number of Firefox threads active while I have only two tabs in use, and memory usage running rapidly up to the 50-70% range (I have 16 GB). While I'm not qualified, it seems there may be a memory leak issue. The situation clears itself after a just few or a few tens of seconds, but then may recur within a minute or so. This started a few weeks ago, now happens almost daily and is making Firefox, my preferred browser, somewhat unusable.

My system: Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz 64-bit operating system, x64-based processor Windows 10 Pro OS Build 19045.4842 Firefox Version 115? VPN Windscribe Version 2.10.16

Somebody better answer me as I am about to switch my default browser from Firefox to something else. I have already asked this question but never received any response. For a long time now I keep running across sites that do not work on Firefox. It can be a streaming site such as Paramount+ or it could be my phone service site Ting. In all of the cases and there have been quite a few I am always able to find another browser the sites will work on. 9 times out of 10 they will work on Chrome but I have found at least one that does not work there but will work on Edge. So, right now Edge is the prime candidate to switch to. I do not want to quit as it would be a pain in the ass as I have been a loyal user for at least 15 years and have stuck with you as I believe in what you are doing and represent but it is becoming to much of a pain to continue using you because I like the convenience of using only 1 browser 99% of the time. I hope to hear from somebody this time. If not I won't be here for much longer. Thanks, Bruce Hansen [email removed from public forum]

When trying to use one particular website on Firefox, I get a message that I am blocked because of an ad blocker but I have not turned on any ad blocker in Firefox. How do I find out if an ad blocker is enabled on my Firefox and, if so, how do I turn it off? I have ensured that the ad blocker option in settings is unchecked and even added this web site to permissions but to no avail. Can someone help? Here is the message I get but none of the steps in this message I am told to take show up on my screen:

Adblock Plus Instructions

   Click the AdBlock Plus icon in the extension bar.
   Beneath “Block ads on”, click the large blue toggle next to “This website”.
   Click refresh.

Were these instructions helpful?

How do i get the search URLs from the previous browser to pop up log-ins automatically to favorite sites when beginning to type in the URL ? Like using an old Social Media links - Rumble or Facebook .login ; or an Ebay log in a gmail log in?

Do i need to restart the computer ?

I would like Firefox to save my usernames for sites, but not the passwords. However, Firefox insists that I supply a password before it will save the account details, and if I supply a dummy password, then it will not let me later edit the account and delete the password. I like to remember my own passwords rather than store them anywhere.

I have tried password managers and they are overbearingly controlling, particularly given that they don't store my passwords let alone my 2FA details, so I'd rather just use Firefox's less onerous, built-in system, if only it would allow me to save an account without a password. Surely saving a username without a password is a safe option, so why block it?

Firefox is set to the English (UK) language on my Windows 10 PC but I occasionally see Spanish words shown after the English word. Eg. BBC News provides trusted World and UK noticias news as well as local and regional … The word (in this case "noticias" ) appears with a faint, light blue background. Here's another example "BBC Business brings you the latest in Business news and cobertura from … Again word (in this case "cobertura" ) appears with a faint, light blue background. I've tried all the settings that I can find in Firefox and everything is set to UK English.

I do not understand why AFTER I used Firefox Delete History that my Charter.net email can no longer be accessed.' I have had Spectrum technicians over here, it is not in their wiring, or outside lines. They cannot go further. I attempt to log into Spectrum & this message comes up - A RED !,followed by This feature is currently unavailable. Please try again from HOME or contact us for assistance. IDID-4000'

I AM AT HOME! I worked/talked with 4 different Charter/Spectrum people on the phone over a 3 day period. briefly I was able to get into the Charter account (Necessary because my VA & other medical appointments/communications are via charter.net) using Microsoft Edge. I no longer can. I am getting that message on Edge as well. I do not want to use Edge or Chrome, I want to use my Mozilla/Firefox/Thunderbird But that is another issue which I cannot get resolved. My monthly contributions to both get through but I cannot even get into Thunderbird for Months & can't get help. At 83, I am computer challenged. Nobody wants to make house calls. What is wrong? What can I do? What do you suggest? Kat Hall

I'm really shocked that the developers at Firefox has not at all fixed the memory leak issue, which caused my PC to crash three times in a row. This is clearly unacceptable; even other browsers I use don't eat up a lot of RAM in a matter of seconds that ends up my PC lagging, or worse, crashing as a result. To the Firefox devs; why are you overlooking an ongoing issue that should've been easily fixed from the get-go, especially with updates that obviously have nothing to do with the memory leak issue? It's really easy to make such a popular browser not hog up memory so easily without causing so much lag, even on higher end PCs.

If the memory leak issue isn't fully resolved by greatly reducing memory usage, especially if I'm only using one or two tabs with me, I will have to consider seeking for another working browser that does not have a memory leak issue, and remove Firefox and never reinstall it altogether.

I want to access a banking site (Capitec.co.za) but am unable to land on their splash page - I just get a blank page, and wait. I can get access via TOR or Opera. I was told to enter using SAFE MODE "Shift+R+Firefox". Anyone know what the issue is? Without guessing. Windows on Thinkpad.

firefox will not link to Jet2.com
