Firefox コミュニティフォーラム

On various websites with embedded podcasts, when the file goes past 1h the volume 'slider' goes away and becomes a basic mute/unmute button. How can i force Firefox to always display the volume slider?

I understand that Firefox relies on both intermediate and root CA certificates for verifying add-on signatures. There was a recent incident where a root certificate expired on March 14, 2025, as noted in the following article: https://support.mozilla.org/en-US/kb/root-certificate-expiration

Could you please let me know the latest validity period (expiration date) of the root and intermediate certificates currently used for add-on signature verification in the latest version of Firefox (139.0.4)? I understand the certificates involved may vary depending on the add-on, but I would like to confirm this specifically for the following add-on:

Thank you in advance for your assistance.

Sending this using Safari because Firefox is totally messed up. Firefox 115.24.0esr (64-bit) OSX 10.13.6 High Sierra 2011 Mac Power Book (MPB) with 16 GB RAM. Verizon DSL line, download speed tests from 10-14 Gb/sec but Latency is always 400-900+ msec. No way to measure Jitter with speedtests that will run on my older system, or Bufferbloat now that DSLreports has gone dark.

I want a tool that will allow me to see all the attempts to connect, and packets/traffic, to see it its my old computer going bad, Firefox, the wireless or wired connection to the DSL modem/router, or the DLS modem/router itself, such as a problem with reaching the Domain Name Server (DNS) etc.

I can access the DSL modem/router in the browser, but there isn't much documentation. Its made by Actiontec but customized firmware for Verizon.

The problem persists whether I am using wifi or an Ethernet cable.

My wifes 2010 MBP computer with 8GB RAM using about 6.4GB, running High Sierra and Firefox 115.24.0 (esr) seems not to have the problem at all.

Firefox will show something in the lower left corner, "connecting to..." or "loading..." etc. It can stall with either status.

Search engines would be StartPage or DuckDuckgo. With DDgo, sometimes it just spins forever, but if I click on the URL bar, it drops down another line with the same URL and "--Visit" appended. Sometimes that will load, but seems random.

Some URLs / links open in a few seconds, some spin forever.

I first called Verizon Tech support on May22 about problems (see full exchange of repeated calls & new trouble tickets below). I think, IIRC, this happens to be shortly after I upgraded my Firefox version. They have admitted to PINGs not returning, packet loss, no excuse for the Latency.

I do have a lot of pages/tabs open; Activity Monitor says my memory use is about 14GB, but the Memory Pressure stays low in the green. I also run Thunderbird, TextEdit, maybe Adobe Reader and Excel. But even when I close everything else, the non-loading issue persists. When I shut down Firefox, the memory pressure can go into the red and take a very long time (so I always shut down all other apps first). A recent shutdown stalled & I ended up losing many open pages/tabs, but even the slimmed down load has the same problem.

I have shut off the AddOn NoScript, but the problem persists.

2-3 working days for networking team to resolve

THUR 22MAY25 call back from networking guy. they raised the speed to 13.4 but latency still 28, he says should be 15 max. Asked him to optimize by reducing download speed. will call back later or tomorrow.

I'm using Google Docs in Firefox. Every time I right click and then click paste I get a message explaining that Firefox is incompetent and I need to hook my keyboard up to my tablet and use Ctrl + V. And tap/clicking Edit > paste won't work either. I use a mouse with my tablet, but not a keyboard.

How to I get FireFox to allow me to use Right Click or at the very least Edit > paste? Even Opera Browser can paste in a Google Doc.

updated my wife's computer firefox to 115.24.0 (esr) and the profile data is lost (bookmarks, addons...).

Went to about:profile and it says PROFILE IN USE: default esr which is the 5th out of six profiles, top to bottom. It should tell me the creation date for each profile.

The 6th in line says "profile: default -release" Is the last in line the NEWEST profile? Should I set that one to be active ( ie the "default profile)?

This usage of the word DEFAULT in multiple meanings is confusing The display should number each profile and tell the user which is the oldest to newest.

This is acting like it is a new version, not a mere update - the user should be warned before he is allowed to perform that process, and given links to what will need to be done to retrieve the previous Profile.

I'm seeing a new trend with websites that use cloudflare like restaurant accounts, Ace Hardware, and freecycle.org. Cloudflare either rejects me upon clicking it (freecycle), or it keeps cycling with its checkbox and doesn't do anything else (Hyatt). I contacted freecycle.org and they didn't know the reason. However, I can get through cloudflare using the Chrome browser. Is this fixable, because I really want to stay with Firefox? I am up to date on my drivers, Win10, and Firefox. Thanks!

I updated Firefox and all my plugins except for Grammarly were deleted, I saw another post talking about going into profile folder but I couldn't find anything about that

Some web sites such as Amazon have an options bars to select items like 'review order'. When the web page first comes up, they show white in the dark bar. But Firefox is immediately changing the white to purple so that it is almost impossible to read. I haven't been able to find anything in settings to correct this. I do not have this issue when I use Chrome.

hi in current version of ff on a win 10 pc.

i have somewhere a fold in ff called "cars"., can anyone tell me how to locATE IT

the advice i previously got no longer works THAanks

Hello Team My name is Sergii and Im C# Automation engineer and working with desktop automation for Firefox (latest version, 139.0.4). I have noticed interesting issue when for some VDI's (Windows Server 2019 Standart, OS Build 17763.7009) Firefox doesn't have Desktop Automation ID, while for my Windows 10 and Windows 11 machines everything is visible (Please checks screenshots). Do you know how to fix this? I have tried to install browser through the same Firefox Installer.exe file but looks like server detecting another OS version and downloading some another file... Thanks!

I've had this issue for years, but it was always something I could live with. The Issue would only appear once every week or so. However, recently the issue seems basically happen on a daily basis.

After Firefox has been running for some time and there's a few other tabs open, The YouTube UI will periodically become completely unresponsive.

Just moving the cursor on top of Youtube will cause 100% + CPU in the Firefox task manager and the page is entirely unresponsive during that time (except video playback)...

This issue has persisted through reinstalls, new profiles and is also present without extensions.

This is a performance Profile of the Issue: https://share.firefox.dev/4kNlhKD

I took a look today and I had 237 MB in cookies! This was after clearing the cache of all files. I've only had this (new) machine a couple months.

Short version: Sites have "cookies" from 200kb to as much as 34MB! For many of the sites over 3MB I have no account and have visited them only briefly.

To be clear, I don't care about the space being used. It's trivial. But what the heck is FFox storing and calling it "cookies"? Last I checked, a site was still limited to 4K size cookies and perhaps 50 per domain. So how are we getting to MB+ sized "cookies" per site? Again, the cache was cleared, so what's left aside from trivial cookie files of <4KB?
