How much money are the bugs costing the company vs. how much money (time) it costs to fix them? Classify your bugs on scale of impact on end users, profit loss and other important factors. Depending on the amount and scope of the bugs, one idea is to have a bug fix sprint, I use that term loosely, essentially a time box to work on bugs and make things nicer. When the time box is over get back to feature work.

Using libraries and frameworks gets you speed in delivery because you don't have to write that stuff yourself, the downside is there are likely bugs in that software or in how your system interacts with it. No software will be "bug free", striving for that is a fool's errand.
