If she leaves the UK, any immigration application currently before the Home Office is automatically considered withdrawn.
Is either the sponsoring child (your friend) of the applicant (the mother) or their spouse an EEA citizen?

One of my friends apply for his widowed mom's dependent visa
Precisely what kind of dependent visa did they apply for?
Did they apply for an Adult Dependent Relative visa? If yes, be aware that the failure rate of that visa,
after appeals, is ~80%. And it has quite high and very precise requirements, i.e. "She has no one back home to take care of and two of her kids living here in the UK and married and British citizen" won't be enough.
If they applied for an extension of her visit visa because of Covid, that will likely have come to an end or will soon, as the Covid restrictions are removed.

if she ask for her passport then her last 2 years' visa processing continuity will break
Not sure if there is any continuity, but that depends on the specific visa that she arrived on and the specific visa that she has applied for. More details on those points and the points above would help us advise you further.
Also, check with the solicitors (if they have applied using a solicitor) if they have heard back from the Home Office.
