It used to work for me for some time. Had this exact error before. Solved it by reinstalling playwright-firefox setting ```
process.env.PLAYWRIGHT_BROWSERS_PATH = "0";

it worked for sometime. But its happening again.

The problem is with the profile directory passed to firefox (C:\Users\mypc\AppData\Local\Temp\playwright_firefoxdev_profile-*). Looks like it doesn't exist or there are permission issues, it might be that someone deletes it while playwright is running. I'd guess that it might also be free disk space issue on your C: drive. Can you check that the directory passed as -profile argument exists while playwright is still running?

[Nisthar]

@yury-s I can't find the profile directory in the app data folder. (Sorry if i didn't included that above) I can see a bunch of other playwright_firefoxdev_profile-* folder but not the correct one. I have like 95gb free space on the drive. I understand why it works for a few time in the beginning and not now.

It also worked a few times after i set process.env.PLAYWRIGHT_BROWSERS_PATH = "0"; and its giving me the same error now.

@yury-s: We auto-create these folders for the execution and auto-delete them after, I don't think they pass any -profile.

i am facing this issue when running multiple instances of firefox in parallel.

running in serial does not cause an issue.

so it might be that each time the next instance starts, it deletes the user profile of the previous one?

if that is the case, shouldn't we create a folder per instance with different name?

thanks!

i am facing this issue when running multiple instances of firefox in parallel.

@devmondo could you please share the snippet to help me reproduce locally?

[devmondo]

@aslushnikov thanks for the support!

unfortunately i cant share the private code, but it is nothing special really.

import {firefox} from "playwright-firefox";

async function runBrowser(){
const browser = await firefox.launch(); 

await browser.newContext({
        ignoreHTTPSErrors: true,
        viewport: null,
    });
    }
    
 await Promise.all[runBrowser(),runBrowser()];
    

please let me know if i could help more.

thanks!

@devmondo ah, two browsers simultaneously! Awesome, I can repro now! We'll fix it shortly
