I use the read aloud function of Firefox regularly and it keeps skipping important parts of the texts! Attached is a screencap of the article I was reading today, the most recent example of this (https://www.analystnews.org/posts/to-understand-the-israel-palestine-conflict-start-with-these-two-simple-questions). I have highlighted the sentence the reader skipped. Do I have a setting not marked properly? What can be done to fix this?

I use a MacBook Pro. I recently created a new profile for Firefox (for work purposes) and set it as the default profile, because I'm trying to get off Chrome entirely. The preexisting no-longer-default profile contained all my "personal" data - bookmarks, extensions, etc. Continued using both profiles for about a week with no issues. Last night my MacBook updated and when I reopened Firefox, the new default profile was fine, but when I went into about:profiles and launched the secondary profile in a new browser, it was completely empty - no history, no bookmarks, no extensions, nothing. That's at least a year's worth of data completely gone. I've looked through support articles and past folks' questions and am just completely lost as to how to restore it or what went wrong. If it's not possible to restore that data, how can I at least prevent this from happening again? I've very much lost trust in Firefox profiles because of this. Help please?

Since yesterday any streaming services such as Netflix or Hulu will only have green screen for the video. The sound will come through just fine and subtitles. My Wildvine is updated, I've toggled the DRM on and off several times, no changes. My browser has been checked for updates. Not sure what else to try at this point.

I am using Windows 7 and Firefox 115.5. When I close Firefox, it stalls and after a minute I get an error message saying Windows Explorer is hung up. Then if I can get an option to close the program. I have tried many ways to exit Firefox but nothing helps this. Thanks.

Mozilla is crashing since last 3 days and it is often

Please do the needful urgently.

Firefox has crashed repeatedly when I've switched tabs to my gmail in the past ~15 minutes. It happens in "troubleshooting mode" as well. I'm running firefox on a linux computer, and my ubuntu installation and firefox are both up to date.

Here's my crash id: bp-b079d597-fb83-4a69-ab65-896370231129

Hi,

I'm getting errors when trying to make online card payments with Firefox. Things like, Invalid card number, not being able to type number in box provided, (No Cursor). It works ok on some sites but not others. However, if I switch to the Edge browser all transactions work perfectly. This has been happening for some time (Windows 11). I'm thinking this could be a bug but not sure.

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?

Hi,

I experienced at least two times recently that the browser on windows 10 looses all the opened tabs and pinned tabs too. Last time it did also that when I closed the program and it opened itself again immediately without tabs and closed itself down again. Next time I opened the program there was no opened tabs at all again. I have the latest version for windows 10.

What do you suggest me to do?

Thanks for help! Br, Balint

I have no audio from Firefox browser. Every other browser and app on the PC works fine. I have tried reinstalling Firefox, and using other Audio devices (speakers, different headsets, etc)

Running on an M1 Ultra Mac Studio, Firefox struggles to play 4K videos in recent days where it would've normally performed fine. I've never had troubles watching 4K YouTube on Firefox, until the past week or two. There are no other applications running, and only the one tab open in Firefox. Just a regular 4K video. Why won't it play properly? Why does it start buffering randomly when I can see my network is just fine? Why does it just randomly skip 10 seconds every minute or so while playing? This exclusively happens on 1440p or 2160p (4K). Please fix this ASAP.

bold textWhy is Mozilla Firefox BLOCKING Kaspersky products, especially Kaspersky Password Manager? It has become an continous on-going problem with many,many people using Firefox which will definitely result in Firefox loosing many users.

Is this another USA bigoted anti Russian propaganda SETUP? Kaspersky is without question, the best protection software on the market. It just works, which is more than can be said about Mozilla Firefox.

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

Firefox is my browser, and Outlook my email program. After years of troublefree access to Kickstarter, I now cannot link to the site, neither by Google search, nor by responding to an email link sent to me by Kickstarter. Instead, I get a message which reads:

'You are sending too many requests to Kickstarter at this time. Please contact support@kickstarter.com if you continue to see this error.'

I have contacted Kickstarter, but their response is that the problem probably lies with my browser. Do you have any idea why this problem should suddenly have appeared?
