Hi Kamil,
Thanks for sharing such a detailed description.
First, please open a support ticket and we will help you sort things out.
Regarding Firefox issue, it sounds like you work with the firefox browser LoadRunner brings outside the context of TruClient on a regular basis. Otherwise I cannot explain why it keeps on breaking for you. TruClient uses a specific version of firefox since it compiles with a specific version of SDK. If the browser is being upgraded by mistake (can happen if you use it outside TruClient context) TruClient will be broken as well. If you wish to use the same copy of firefox that LoadRunner brings, copy the folder to somewhere else on your computer and use it freely from there
Regarding Chromium, that is strange. Must be investigated by support. I am sure we can address it. If you are using 12.50, please consider experimenting it also with 12.53.
Sorry for the inconvenience
Regards,
Shlomi
