We are using web application that uses JavaScript batch files, where one of them exceeded size of 15MB. Since then Firefox seems to evict the file from cache and always load it from the server also excluding If-Modified-Since header. When the file size is decreased to former size ( around 12MB ), caching works again as expected: file is either served from Firefox cache or If-Modified-Since header is sent in request to verify if server file changed. When I checked difference between files server, there was nothing changed except file size and content ( i.e. there is no dynamic changing of file, cache headers stay the same, ... ).
Is there some configuration setting or hard-coded limit which forces Firefox to evict larger files from cache and enforce their reloading?
Here is the list of selected response headers on mentioned file:
X-XSS-Protection: 1; mode=block X-Content-Type-Options: nosniff X-Frame-Options: SAMEORIGIN Content-Security-Policy: frame-ancestors 'self' Expires: Tue, 22 Sep 2020 07:43:13 GMT Cache-Control: max-age=31536000 Cache-Control: public Last-Modified: Thu, 01 Jan 1970 00:00:00 GMT ETag: "0" Content-Type: application/javascript;charset=UTF-8 Keep-Alive: timeout=5, max=100 Connection: Keep-Alive Transfer-Encoding: chunked
Thanks for any hints.

No Top sites when I go to HOME page, No Top sites OR Home Page when I open new tab. (Just a blank page), Top sites check box is 'ON', This is a fresh windows 10 install, Latest Firefox version is installed and has been running for several days now. It shouldn't be this hard to get top sites working again. It has to be something simple preventing all top sites from being displayed.

Firefox has a serious problem. Within a few days of refreshing it, it starts to bog down and becomes noticeably slow.
I almost gave up using it, but then found the refresh function. The first time I did this, it sped things up nicely and I retained everything. Within a week, Firefox slowed down again. So, in frustration, I reset it again. This time it did strip all my settings and saved them in a folder on the desktop.
I have seen the solution that things can be copied from this profile folder into the new profile folder.
However, I have to say that from a usability perspective, this is a real fail. To ask users to selectively copy files even once is just a pain in the ass. To expect them to do it once a week (at least) in order to keep Firefox running crisply is ridiculous.
I implore the Firefox team to come up with a better solution to help users keep Firefox running smoothly. I know it's complicated and that add ons are the real issue. But there's got to be a way to make this process more user friendly. Even just a notification when the browser senses itself slowing down that points to a well written, step by step troubleshooting guide would be good.
Or perhaps a refresh that disables addons but keeps the rest of the data. That might help people more quickly realize that an addon is causing the slow down (assuming that is the case).
I don't know what the best solution, but there has got to be a better way than refreshing, losing all data, and then being expected to selectively copy information into a profile!
Thanks!

To anyone who has experience or expertise in working with the integration between Bentley Systems softwares and Firefox - especially ProjectWise WebServer,
I would like to ask why am I able to download the file with Firefox but not with other popular web-browser such as Google Chrome, Internet Explorer nor Microsoft Edge. For more technical information, the below list is the required “extension” for the browser to work correctly with ProjectWise WebServer.
- ProjectWise Web File Transfer ActiveX Control - used by any operation that downloads a file to your local web parts working directory - Bentley DGN Navigator Control - used by the ProjectWise Navigator web part - VPR ActiveX Control - used by the ProjectWise Publishing and Markup web part - Spatial ActiveX Control - used by the ProjectWise Spatial Content web part
If you may required to know more about web URL link and due to company privacy policy, I can only share the format is something like https://wsg.“companyname”.com/“server directory”
In conclusion, I would like to know what makes Firefox able to while others can’t.
Regards, Donovan

The new private network extension is very cool...when it works which is most of the time. I am running version 69.0.1 . The install was perfect. I turn on the extension and go to a website that checks your IP address. OMG, not only is my IP address an address provided by Cloudflare, Mozilla's partner, but I now have a Cloudflare IPv6 address. That was a surprise. My ISP, Verizon FIOS does not provide IPv6 but a Firefox extension does. I am happily surprised.
The problem is that for no apparent reason connections to any website will stop working. I see the TLS connection message in the lower right but the webpage doesn't load. The fix is to turn off this extension for a few seconds and then turn it back on. Everything will then work. This occurs about every five minutes.
How can I troubleshoot this?
Thanks.

Firefox has been extremely laggy and slow lately. I've tried every "quick fix" I've found online, to include refreshing, sfc /scannow, disabling extensions, re-installing firefox, running malware scans, etc. This started after a cluster of windows, firefox, NVIDIA updates about a week ago, and I haven't been able to pinpoint the source of the issue. So far the only thing that brings the browser back to full speed is restarting my computer with an offline Windows Defender scan. It never actually finds anything, but when the computer restarts Firefox works at regular speed until it is locked for a couple hours or restarted. Any thoughts?

From around 5 months ago when I download "any type of file", I sometimes get an empty dialog box except for the very top line "opening xxxxxx.xxx". i.e. there is no "You have chose to open....What should firefox do with this file, open or save file etc. " Usually this corrects itself when I try to download the file again.

Login to the New York Times is in a permanent loop. You login in the usual way, and the page loads without logging you in. It tries to sell me a subscription when I already have one. I have already cleared the cache and cookies and suffered having all of my websites broken by Firefox forcing us to re-login to everything on the web over and over because we have to go through the ritual of clearing cache and cookies over and over because Firefox is always malfunctioning. I have already permanently disabled "hardware acceleration" and have done all of these multiple times, numerous times. It's undoubtedly Firefox built in security devices that are causing this block. Chrome does not cause this, but there are other reasons not to use Chrome unless I have to, which is what I now have to do because of Firefox hyper-intrusive "security" software. If I could disable all the security bloat in Firefox, I would do so. It's just impossible. It does on month after month, year after year. We are prisoners of these device builders!

Firefox almost always crashes on closing. If I reopen firefox within a couple mins of closing it tells me it can't open because it is already running. If I leave it closed usually after several mins I get a notification that it has crashed. I've tried disabling all add ons/refresh/disabling sync etc. with no luck so just trying to see if anyone has any ideas on possible culprits. This is on multiple Win 10 machines, can post more crash reports later tonight. My other system it happens every single time I close it.

The passing of Windows credentials into our homepage using a mozilla.cfg file isn't working properly and I can't figure out why. I know Firefox is reading the config file because the homepage is correctly pointed. However I have edited the following settings to:
lockPref("network.automatic-ntlm-auth-allow-proxies", true); lockPref("network.automatic-ntlm-auth-trusted-uris", "servername.domain.corp"); lockPref("network.negotiate-auth-allow-proxies", true); lockPref("network.negotiate-auth-delegation-uris", "servername.domain.corp");
This is what the settings are for the homepage: //set intranet as home page lockPref("browser.startup.homepage", "https://servername.domain.corp"); lockPref("browser.startup.homepage_override.mstone", "ignore");
When I open firefox it directs to our homepage, however it prompts for credentials. Am I missing something?

Hello,
I am having bit of a problem with the cookies in the latest Firefox 69 and the 69.0.1 update that I had just now. In the Firefox I had Cookies and site data permissions set to allow specific sites for the current session and now after the update looks like those cookies are getting blocked... I always have been using private mode and I had disabled all the cookies. Looks like a bug, right? I think I could try add exceptions to the Content blocking, but then again, other stuff apart from cookies will be allowed. Running browser in the safe mode gives same result.
I would appreciate some help to resolve that issue. Thank you.
