Firefox very slow for www.finvasia.com, unable to do trading in firefox
I support open source movement and against tech giants and hence I love and want to use Firefox. I would use Firefox even if it is slow because on most sites delay of few seconds doesn't matter. But I do stock market trading and trading website of my broker (finvasia.com) is very slow in Firefox. On all chromium based browsers slowness is not there.
In trading delay of even one second is a matter of profit and loss (specially in scalping) and hence using Firefox is not possible as it is very slow for finvasia.com.
I have done screen recordings to give an idea of degree of slowness. First video is when finvisa is opened in a chromium based browser MIN. As you can see that when I change from holdings to position etc then delay is very less. (the yellow circle on the screen hardly complete one complete rotation and holding or position scree is opened). In this video you can also see that when I place order or modify it, everything happens so quickly.
Finvasia on chromium based browser
But in the below video (finvasia in firefox) you can see that when I switch from holding to position (00:2) the yellow circle (just above the pointer) makes 9 complete circle before showing the screen. When I click on Buy button on order screen (00:34) the order doesn't get fulfilled (the order rectangle didn't disappear). At 00:47 it said connection issue (There is no connection issue, wifi is working fine and never show any connection issue in chromium based browsers but in Firefox it shows in every order).
I kept waiting but order rectangle didn't go so finally I had to close it manually (1:45). After that when I switched to order screen it didn't show any single order. I tried to refresh the order screen (1:59) but nothing happened. So finally I refreshed the tab of browser. It was also hanged and after few click it worked and then you can see that there were many orders on order screen.
As trading involves money and such delay can cause huge loss. Trading on Finvaisa.com is not possible if a person is using Firefox.
I also tried safe mode, and refreshing the Firefox, but problem didn't get solved. Kindly fix this problem.
Firefox version is latest (99) and I am attaching screenshot to give details about my system and OS.

Hello! Can you try disabling the Enhanced Tracking Protection: Enhanced Tracking Protection in Firefox for desktop You can also try clearing cache, cookies, and site data: Clear cookies and site data in Firefox How to clear the Firefox cache
@elison I tried all suggestions told by you but problem is still there. Here is the screen recording of me trying your suggestions. Tracking disabled and chache cleared, still the problem is there.
I tried to monitor network in developer tools. I don't know much about developer tools but it is showing following errors for finvasia.com. Can these errors be the cause of slowness?
Edited later:- This image is of Librewolf which may cause some confusion and hence I am clarifying by editing this post. The problem is in Firefox and was tested on Firefox. All the videos given in the post and comment by me was of Firefox and not of Librewolf. Only this developer tool test was performed on Librewolf.

Is there a reason for old version of Firefox? Like you said time is money so should be on current version which may help with performance. The site loads for me in 0.6sec. Did you try the same steps with Firefox from Mozilla? https://www.mozilla.org/en-US/firefox/all/#product-desktop-release The video wouldn't play for me on Mac, you should've just put it on YouTube. Who are you using for DNS?

Do you have enabled "Resist Fingerprinting" if you check this pref on the about:config page?
- privacy.resistFingerprinting => false
@jonzn4SUSE, I don't think version 99 was old yesterday. How can the site load for you in 0.6 seconds? It seems to me that you tried to understand the problem without watching the video (as you said it was not playing on Mac). If you just visit the site obviously it will load within seconds. Because home page of site is not the trading terminal.
When you log in the trading terminal on the site and then try the transaction during market hour then only you can see the problem in Firefox. I highly doubt that you have a trading account on that website. So loading of homepage of site within seconds has nothing to do with the problem shown by me in the video.
I installed Firefox from official repository of Arch Linux and hence I don't think it is different from the one downloaded from Mozilla site.
My DNS also doesn't matter, because on same DNS on same ISP this trading site is working absolutely fine in every chromium based browser (Brave,Min etc) and even on Qtweb engine based browser like falkon. So problem is with Firefox and not with DNS.
@cor-el This problem can be tested only during market hours and Indian stock market is closed till Monday. I will check on Monday and will post the result here.
I'll update the tag because it was showing Firefox 91.0 which is why I asked the question. Good luck
Showing the Firefox version in the user agent as 91.0 was actually the reason I asked about "Resist Fingerprinting" because that changes the user agent to the current ESR (91.0) among other changes that might affect/confuse websites that use browser sniffing.
@jonzn4SUSE @cor-el I am unable to understand where the user agent is 91.0? In every video I used Firefox 99. If you are talking about the browser details captured by Mozilla while creating the post then the post was created in Librewolf and Librewolf spoof the version number. I think to clear all this confusion I will record a complete video with voice, on Monday, where I will show everything version number, safe mode etc. Till Monday Indian stock market is closed hence it is not possible before Monday.
As promised this is the latest screen recording demonstrating the problem in Firefox. In this screen recording I have shown that I am using latest version of Firefox and checking this problem in safe mode of Firefox. I have even shown that there is no problem in my network and RAM is also available in sufficient quantity. This screen recording is one continuous screen recording without any cut or editing.
Demonstration of problem with version number of Firefox in screenrecording.
You mention that you are using the version from the Arch repo. I recommend that you try a version directly from Mozilla:
@Seburo The problem is present even in the Linux version downloaded from Mozilla's website. Here is the screen recording. Problem present even in the Firefox downloaded from Mozilla's website.
But I have found one thing. This problem is present in version 99 of Firefox and previous versions of Firefox but not in Nightly version 101.0a1. Should we assume that the problem is solved and I just need to wait for stable version 101?
Today I tested this website in Firefox Beta 100.0b8. The problem is not present even in Beta 100.0b8 version. So I think the problem will fixed once the stable 100 is out around 3 May.
I am using Firefox 100 from past many days and can confirm that problem is fixed in Firefox 100. So now it is not a problem for me, but I am thinking about users of ESR version on Debian. I check in Debian. The latest version of Firefox ESR (91.10.0) available in Debian still has this bug. Any chance that it will get fixed for the users of ESR version?
