I am trying to turn off my cache settings.

The instructiuons given tell us to set 'network.http.use-cache in about:config.

I have tried that, and that Preference name no longer exists.

How is this achieved?

I need this for Automation Testing. Currently, cached data casuses tests to fail.

Hi,

It's the second time today i see a video with this codec (as stated by VLC) : H264 - MPEG-4 AVC (part 10) (avc1), that's not visible in Firefox, while it's audible. Here is the video url : https://web.poecdn.com/public/news/2018-05-02/VLS_news.mp4 Previous one that also didn't work : https://web.poecdn.com/public/news/2018-04-17/NewRainofArrows.mp4

Some working with the same codec, still as stated by VLC can be found here : https://www.pathofexile.com/forum/view-thread/2034078 ; Change : Different CDN, no sound in these video. For a direct video link, here's one : https://imgur.com/BySFQ45.mp4

Not sure what's the issue here, if there's something new unsupported in openh264 or if it's just an issue for some users. I know i'm not the only one experiencing it, cf. https://www.reddit.com/r/pathofexile/comments/8csmvo/skill_revamps_part_3/dxhi8f6/

Edit : Seems like Imgur uses x264 (http://www.videolan.org/x264.html) to encode their videos (ftypisom : MP4 Base Media v1 [IS0 14496-12:2003]), while GGG (poecdn) used something else (Mainconcept Video Media Handler ; ftypmp42 : MP4 v2 [ISO 14496-14]).

Edit² : Bug report.

Hi! There is a bug. YouTube History is not saved when i use Firefox as browser. So I deleted it and then reinstalled it, logged in to it and played videos from YouTube again. Then i checked again the history and saw that it was saving. Later without any changes in Firefox settings (including addons), the problem began starting again. I still don't understand why it is happening. The addons that i have installed are: Kaspersky Protection, Malwarebytes, uBlock Origin and Privacy Pass. This problem doesn't happen when i use Chrome Browser with same extensions.

when I click on the frontpage, nothing happens now since the update. Also the arrow is gone to read the next page and it is impossible to consult the older newspapers (archive) - see examples.

By using Google Chrome everything is fine, no problems at all, I can read my newspaper as usual.

So the cause of this bug is Firefox!!!

Currently using FF 63.0.1, but I'd hoped that upgrade would resolve the ongoing problem.

Extensions work normally after reboot, but within a day, are again missing. Eg. scroll up/down initially available, but then symbols disappear from page. Others in toolbar look fine, but do not activate when I attempt to use them. When I restart FF, it's back to functioning, but only for a short time. frustrated.

This dirty trick required to move a single bookmark folder from one Firefox profile to another stopped working for me for some reason. I tried different firefox versions, including the one from portableapps.com, I tried starting the second instance with -no-remote switch. Nothing worked. When I tried drag&drop between the instances there was the blue feedback dash indicating the place where the folder was going to be dropped in the target Library window. But nothing happened. I tried holding Ctrl as well, also using Ctrl+C - Ctrl+V key combinations.

Is this a known issue? Has a recent version of Firefox removed this ability?

I hate that I have to ask this.... I have been trying to import my username/passwords from Chrome to Firefox for weeks. I'm using the Firefox built in Import tool. It just simply doesn't work. A couple of weeks ago it did actually import 1 site/username/password. Then today I was able to get 1 more. Both of these were sites that I used Chrome to sign into recently, like it cached them or something and thus were able to be imported into Firefox. But all the others that are saved in Chrome will not come over. I just don't get it. There is really nothing to it, so I know I'm doing it right. Options>>Privacy & Security>>Saved Logins>>Import>>>Select Chrome as browser to import from>>(Deselect cookies, browsing history, bookmarks) Saved Passwords selected>>Next>>Finished. Nothing.

Maybe I should uninstall Firefox and reinstall it and see I can do it from a fresh install. I don't know. Very frustrating.

Version 66.0.3 64 bit.

Thanks

Description of the problem is as follows: 1) I start a presentation on Google Meet 2) I choose to present one of my open windows (*not* entire screen) 3) window is being presented, just fine, 4) If I *minimize* the window being presented, the tab crashes. 5) the problem does not occur if I present the entire screen, rather it has to do with the window being presented becoming minimized.

Win10/drivers/Firefox all up to date - problem persists even in Firefox's Safe Mode.

Web pages are loading painfully slowly, 11-34 seconds, some never load before timing out. Other browser (Edge) is loading pages quickly. Internet connection reasonably fast (35.7 Mbps). I tried the following:

  - Safe Mode, no change.
  - Refreshed Firefox, no change.
  - Disabled Antivirus and Firewall, no change.
  - Disabled Network Proxy, no change.
  - Content Process Limit set at 8.
  - Firefox is using 550 MB of memory (out of 10.2 GB)

There are instances when Firefox does load pages quickly, but they are increasingly infrequent and not predictable.

Hi, For the add-ons section, I think all the add-ons should be scanned.

=================

it is not my fault that if I download an add-on, it turns out to be a malicious add-on that executes remote codes. You are telling me: "This is not monitored for security through Mozilla's Recommended Extensions program. Make sure you trust it before installing." How can I trust it if I don't know anything about it?? or if it is new? -Most of people here who are downloading add-ons are normal users like me, not people who understand codes and developing.- Read reviews?? Do I understand from you that some people have to sacrifice for us so the rest can know if it is bad or good add-on? And by the way Reading reviews is not enough, For example Few months ago I downloaded a VPN similar to another one, lots of reviews say it is good, so I used it for maybe 1 month then I disabled it and stopped using it. Today I look at it in the disabled add-ons list, I find this message: "VPN has been disabled due to security or stability issues." I read more information about it, it turned out that it was executing remote codes....... That means I shouldn't even trust reviews!! Nothing happened to my firefox browser, but (it may happen) in the future, because of the already executed remote codes or or maybe those codes stole some information about me,....I don't know, but it may get worse who knows what those executed codes do.....

=============================

Now after I provided my (((important))) suggestion, I need an advice please what should I do now?? Should I now reinstall this browser and clean it and remove all of the history? Or change my passwords in ((every site)) I visited?? or what? Thank You Very Much.

So after browsing for a while, when i right click (on any page) the popup menu doesn't show up. Also, when this happens, if i click any _folder_ in the Bookmarks toolbar, the popup window containing the items doesn't show/pop up either.

So, i created an entirely new profile in Firefox, without installing any addons or changing any of the other default settings. And, after browsing for a bit the same issue happens again...

Rebooting Firefox fixes the problem for a while. Please advise, thank you :)
