Firefox Community Forum

I asked this a year ago and never saw a solution (other than 'gee, it should work yet'.) I use the local Windows Hosts file to give my router a quick reference name to get into it. That too has worked for years but began to fail last year. Inconvenient. The best I could track this down, it has something to do with forced DNS lookups and skipping the old Hosts file. If so, any work around to get my system simplicity back? Attached is what I see on each attempt.

I tried various settings for DOH and nothing works. I can reference the Hosts file in a Windows Cmd Prompt and it resolves just fine. Something is screwy in Firefox for some time now and I'd like to know what.

Today I was no longer able to stream movies on Amazon Prime or Youtube. I watch Amazon movies most nights, watched last night. Tonight I got a message when I tried to continue watching a tv series on Amazon that I've watched for weeks. It said I had to update Firefox and told me how, but when I went thru the process Firefox said it was up to date. On Youtube I got an error msg. 99,999 . What is happening?

I suppose this is a kind of support question, of sorts, but in my opinion this also has to be treated as a complaint, in a sense.

About one and a half months ago, Firefox became unresponsive, that is, it became awfully slow. I experienced just about every issue with the browser that was mentioned in the following support pages and support issues (posted by others) and I read all of those :

Secure connection and security warning error pages in Firefox https://support.mozilla.org/en-US/kb/secure-connection-failed-firefox-did-not-connect

An oddball situation had occurred in which I couldn't for the likes of me go to my librarything.com homepage at each restart of the previous Firefox session, which also causes lagging when the session wants to connect to the other (normally unproblematic) website session tabs, and I also get multiple connection errors + insecure connection notifications for some of these websites. (sometimes refreshing a page does not help, sometimes it does)

I got bored reading all those support pages and trying out the solutions, because nothing seemed to help. In the long run, I decided to de-install the whole browser after backing up bookmarks, speeddial settings, passwords and the whole profile. Simultaneously, I also tested the connectivity to these websites in another browser (Brave) and this did not present me with any problem.

So I did the following :

1) deleted the whole cache and closed the browser 2) uninstalled FF with Revo Uninstaller (which has an option to remove all remnant files / folders/ registry items on the Hard Drive) 3) made sure to remove all cached leftovers from HD by using multiple cleanup tools in succession : 1) Wise Disk Cleaner followed by 2) Bleachbit followed by 3) CCleaner

Went to the mozilla website, downloaded and installed the last version of FF. Next, imported bookmarks, speeddial settings and passwords. Next, reinstalled the Firefox extensions I used before (without any lag until one and a half months ago). I also did NOT copy the stored profile but decided on starting afresh with a new profile.

Everything worked lightning fast and efficiently until a few days ago, when I received an automatic update of Firefox - 151.0.3 - and all of a sudden, the same problems are reoccurring. And again, I can't connect to an unproblematic website like librarything.com, whereas before the update I was able to without any problem !!!

What the hell is going on with these auto-updates ???

hello all,

I'm running Firefox 115.18.0esr For a month now, tabs have crashed constantly. That is, *every single tab* crashes sooner or later and usually it's sooner. It's making Firefox unusable.

I know my desktop is old and my OS is considered obsolete, but still, I'm a fan of Firefox and want it to work. I'm running OS 10.13.6 (which I can no longer update) on a iMac mid-2011.

Any advice much appreciated.

I can open pages but when I click on the subject it doesn't open. Tells error with net work connection, it's like this with email,YouTube and Gmail, twitter. Thank you.

Hi,

I’m using the latest version of Firefox on Windows 11 (currently v126.0), and I’ve noticed a recurring issue: the browser freezes for a few seconds when I switch between tabs, especially if one of the tabs contains a media-heavy website (like YouTube or online editors).

The browser doesn’t crash, but becomes unresponsive for 5–10 seconds before catching up. Task Manager shows a CPU spike during the freeze. I’ve tried the following:

-Clearing cache -Disabling all extensions -Running in Troubleshoot Mode -Updating graphics drivers

None of these solved the issue.

Is this a known problem? Any suggestions on how to fix or further debug it?

Thanks in advance!

Hey all. I am having some connection issues with my secondary comp. Firefox 132.0.2

I recently moved and am getting my home office set back up. Nothing was changed during the move other than shutting down, unhooking everything and setting it back up at the new home. My secondary comp is used for live streaming various TV channels, Youtube, live radio broadcasts etc. Youtube, Google and Gmail loads and works fine. Several of the TV channels load the page but will not stream. Rumble, the two radio stations I listen to and our website host access page all give me the Server Not Found screen. It also fails to update Firefox. Also, my Thunderbird will not download new emails. Now here is the weird part. I can go to all of these sites on my main comp and everything loads and works fine. Any ideas? I have tried changing different settings but nothing makes any difference. I even disabled the firewall.

Thanks.

I just got a new Epson 3-in-one printer and tried to sign up for the warranty. I got a message that the warranty was expired... I went to the Epson support site on Firefox and Malwarebytes blocked the site as malware... It said I could add the site as approved, but I don't know how to do that. "https://www.epsoncom.com/my-account/home". The Epson site said I already had an account but my password was incorrect. I had an Epson printer more than ten years ago; I don't remember the password and they don't provide an option to reset it. HELP, PLEASE.

On Firefox ONLY, when navigating to multiple sites, I'm getting "Access Blocked. We detected unusual activity from your device or network. Reasons may include: Rapid taps or clicks JavaScript disabled or not working Automated (bot) activity on your network (IP 97.140.47.209) Use of developer or inspection tools." ID: 448c1aee-5d22-9619-629b-3ab812753b6e."

I have email Mozilla for help and have searched for solutions and have found none. Most recently is happened on Etsy. Does not happen if I use Duck Duck Go, Chrome or Edge.

I've use Firefox or Foxfire for several years at the time I installed it I was using Windows 10. I now have Windows 11. Ever time I try to access he internet a window comes up and ask me to create an email address with Gemini. Google or Microsoft will not let me access my internet, [email removed]@nquinnlaw.com. How do I use Mozilla to access my email.

Firefox has become exceedingly slow. I have used Firefox for the most part going back to the beginning save a 2 year stint when Mozilla fell behind and did not update the product in the early years after ver 4. However, the slowness of Firefox is so bad now that I may have to find or use another browser! It is literally that bad! This problem is recent as in the last 45 days as far as my individual needs. I have already gone through the troubleshooting list and made the modifications. That seemed to work for a day or two but the slowness of Firefox is progressively getting worse with each passing day.

The speed is like 3 minutes to 10 minutes when just trying to open a known and commonly used bookmark. Checked against Edge which came with Win 11 and Edge loads within a second or two. So, the problem is not hardware or internet connection. I have one of the fastest speeds on the planet with a true fiber optic connection as I am close to the backbone location in my city. We are talking 2.1gig down and 820MB up. Tested against two different speed tests. The problem is with Firefox specific. Mozilla needs to address this issue as it seems to be an ongoing problem across several IOS platforms.

I browse using full screen in Firefox. After closing the app and reopening, the browsing window is just 1/4th the size requiring me to expand it, every time. Is this a bug?

Currently I can not access any website through firefox without a VPN. Other browsers are working without a VPN. I wonder if now China is blocking the firefox browser. Never had this trouble until today. Maybe it is a new setting i am missing or unaware of?
