Fóram Tacaíochta Firefox

Firefox use a lot of CPU time ( it reaches 100% ) while watching youtube videos in 720p on Windows 10, and videos lags and stutters too much. Not using any ad blockers, non of plug-ins are on. It does work just fine on Ubuntu on the same machine Vids also were working fine on previous popular web browser known for its spyware

Using hardware acceleration is on in browser settings. Specs are: CPU: Intel(R) Core(TM) i5-3230M CPU @ 2.60GHz 4,00 GB x64 Windows 10 Home edition 22H2 GPU: NVIDIA GeForce GT 635M

Firefox version 120.0.1 (64-bit), up-to-date

I am using Firefox version 119.0.1 (64-bit) on Ubuntu 22.04. Using this version of Firefox, as well as previous versions for the last few months, I am having a persistent error when using Google Advanced Search. I enter search criteria into the field “Find pages with … all these words” and successfully progress through a chain of web pages. Previously I was able to backtrack to the previously mentioned field and find my search criteria, then edit the text, and carry out a modified search. For many months this field has been blank when returning to it. So it is now necessary to re-enter all text for a new search. This is very frustrating. I have experienced this problem on the three computers that I regularly use.

I have found that when I use the Google Chrome browser the problem goes away and searches progress normally. I would much prefer to use Firefox as my browser as I find its bookmark system superior. The truth is that if this problem with Firefox can’t be fixed soon I will be forced to migrate to Chrome. Can you please help me resolve this Firefox problem?

Hello fellow Firefox users, I sadly cannot use my Firefox (120.0.1, 64 bits, Windows 10) anymore as it is too slow to show a webpage... It's so slow, that I initially thought that I have no internet connexion at all on Firefox.

Can anyone help me figuring why my Firefox profile is so slow ?

Long story short:

- Until 2023-12-05, my Firefox was working normally.

 My parameters were "No HTTPS everywhere" and "No DNS over HTTPS (DoH)".

- On 2023-12-05, I was connected to an entreprise DNS (Mangling DNS).

 I cannot acces some website because of their local policy, so I changed my DNS parameters.
 I choose to use DoH with Cloudflare instead of the given DNS.
 Internet worked perfectly.

- On 2023-12-06 and 2023-12-07, same parameters, Internet worked perfectly on another network. - Since 2023-12-08, Internet is very slow. It need about 1.5 minute to get start.duckduckgo.com loading on any network.

 I thought it will not load at all (timeout ?).
 Others webrowsers (e.g. : Microsoft Edge) are correctly working.
 The "ping google.com" command is working normaly on windows with 2ms delay.
 The DNS on windows "Get-DnsClientServerAddress" are the normal DNS of the router.
 Even with reverting the DoH parameter to off, I do not get back my web browsing speed.

Troubleshooting :

- It's slow with "DoH and Cloudflare" activated.

 It's slow on my home network.
 It's slow on a public network.
 It's slow on another private network.
 https://www.dnsleaktest.com gives me a list of Cloudflare DNS (IPv4) near me, different from the DNS (IPv6) used by Windows 10.
 Meanwhile, Microsoft Edge, ping and wget/curl are working normally (i.e. no delay).
 Noticably, Microsfot Edge use by default according to https://www.dnsleaktest.com the same Cloudflare DNS.

- It's slow with "DoH and Cloudflare" NOT activated.

 It's slow on my home network.
 It's slow on a public network.
 It's slow on another private network.
 https://www.dnsleaktest.com gives me one DNS from my ISP (IPv4), same value as the DNS (IPv4) used by Windows 10.
 Meanwhile, Microsoft Edge, ping and wget/curl are working normally (i.e. no delay).
 Noticably, Microsfot Edge use by default according to https://www.dnsleaktest.com the Cloudflare DNS.

- In about:crashes there is not relevent crash (only old crash).

- I have not changed any about:config parameters in the 2023-12-05 to today (2023-12-12) period.

- I have run mozregression GUI with no problem.

 The program oppened succesfully start.duckduckgo.com .
 This website was choosen as it is an allowed website on every DNS.

- Firefox 120.0.1 is saying that it is up-to-date.

 And as of today, it is.

- I do have some extensions (12 activated) on my Firefox, so I try without extension.

 It worked but I do not understand why!
 * New profile. Using "firefox.exe -profile" I created another clean profile to see.
                It worked.
                According to https://www.dnsleaktest.com, my new empty profile uses both Cloudflare DNS (IPv4) and the router DNS from the ISP.
                Adding one-by-one most of extensions (6 now) to this new profile do not break yet my Firefox speed.
 * Safe Mode. Using "firefox.exe -safe-mode" I have started my corrupt profile without extension, JIT, etc...
              It worked.
              According to https://www.dnsleaktest.com, it uses only the router DNS (IPv4).

- I can send some result from about:support if needed, but it kills privacy...

Conclusion :

I do not understand why my main Firefox profile is not working correctly. I do not see strange things when troubleshooting. Nothing makes sense.

May someone help me figuring out?

When connecting to a http proxy with a username and a password it says "Proxy server refused connection"

When connect to the same http proxy and turn off its Authentication, it works.

same bug with SwitchOmega & Smart proxy

Stop tabs from automatically refreshing to top of page. Many people have this problem and I don't find a fix. One article states to go to Options and "Warn me when websites try to redirect or reload the page," but I can't find options.

When I open firefox it opens on the "success" page it should open on my selected page Yahoo.com

this happened after I ran the "refresh firefox" option

when I attempt to open firefox, a window opens: xul runner error: platform version 120.0.1 is not compatible. minversion>=119.0.1 maxversion<=119.0.1 If I click the "ok" button the screen goes back to my desktop.

I am having issues with Firefox crashing at various times though out the day. It always starts out fine, but at some point it just stops responding and I have to close the browser and reopen it. This happens at least once a day and it does it on different units (my LG Laptop, Dell Desktops (2 different units-1 at work and 1 at home), Surface Pro 9, my Dell laptop), so I know it is not the unit, it is something in Firefox! My Dell laptop runs Windows 10, all the others run Windows 11. Please look into this and provide a patch. Thank you!

should I just download a new file...suggestions please Thanks

I'm a hiker and backpacker. I have recently begun using AllTrails.com to record my hikes making them easier to share with others as well as to save them for my own records. Everything works fine except uploading photos. This aspect of the app does not work at all in Firefox. It does work with MS Edge and Google neither of which I want to use.

Since yesterday (12-December-2023) and continuing today (13-Dec-2023) when I attempt to use the search bar to answer a question eg "five letter words with three vowels" I receive the message 503 Service Temporarily Unavailable. I can enter Google and can then go to Google for a search.

Hello, when I open the Firefox browser from my taskbar it does not open as a full browser page as Image 3.

I have to click on the full-screen icon twice to get it open in full screen as in Image 4.

Please can you help?

Greetings, all,

I get this error messsage:

<We are unable to complete your request. Our system is currently unavailable.Please try again later.>

when i try to log on to my USAA bank accounts.

Tech support at the bank worked with me for an hour. We changed password, cleared the cache for the bank's apps, restarted Firefox, restarted the computer, all to no avail. I declined to try Google, simply because i don't trust it. Tech support person said another bank customer had had same problem and just changed browsers, which i don't want to do.

TIA for any help.

I have many webpages open in many browsers and tabs. From time to time, FF locks up, and then the PC locks up, and the only way to resolve it, is to restart (eg: reboot) the PC.

On spotify web player in firefox there is a delay after skipping 15 seconds forward or backward in audio. Only on bluetooth speakers. But doesn't happen on Chrome. Anyone got a fix or can help?

Hi:

  I do genealogy and often have 20 or more WINDOWS (not tabs) open simultaneously.  I also rapidly type, copy/paste, between windows, etc. and can instantly detect slowdowns - especially irksome when the mouse disappears for seconds while the system is working.  I keep history and cookies...reminds me of pages I've already looked at when color change is enabled.
  After crashing a hard drive, I finally realized that Firefox was accessing the disk WAY too much.  Even with the system static (no page changes or updates), it was continually writing to disk.  Occasionally, it would take over the disk system for seconds.  Over time (years), as you guys improved, it became less significant; just broken up into lots and lots of small accesses.  Researched quite a bit...

  Started with increasing the sessionstore interval, but still was an issue.

To solve MOST of the problem, I saw a help note. I created and set to FALSE

browser.sessionstore.enabled

Plus modified several other sessionstore items This helped a lot...

   BUT this did NOT regulate sqlite storage for third-party stuff.

This is probably handled and hidden under another config section/ keyword (not called 'sessionstore', but '??thirdpartystore??' or what?) The following profile files are still handling a LOT of writes. I use Ancestry as example (the worst offender actually), but applies to other sites also.

.default-release\storage\default\https+++www.ancestry.com\ls\data.sqlite-journal ...
or occasionally
\https+++accounts.google.com ...

Just for these accesses, looking at 100k writes every second, like pulses. This is with only one window open and a static (no change) page. What changes on a genealogy page that requires updating every second = this is a list of dead people?? Finally, my question(s): What config sections and "keywords" handle these third party writes? Any clue/hint on how to eliminate?

Thanks
